Second plot overwrites first plot in function script

I wrote a function that is supposed to plot two separate pie charts. It, however, does not seem to do this within the function script. If I copy and paste the code in the live script it works. I'm at a loss as to why it won't work. Any suggestions are welcome to improve or fix this code.

Here is the relevant portion of the code:

%Creates blank string to start compiling location names to make legend
blank = strings(1, length(grocLocCats));

%Creates blank vector for compiling cost numbers
blankCost = zeros(length(grocLocCats), 1);

for k = 1:length(grocLocCats)
    y = grocLocCats(k);
    locIdx = strcmp(Table.Location, y);
    cost = sum(Table.Cost(locIdx));
    blankCost(k) = cost;
    costStr= num2str(cost, '%0.2f');
    numStr = strcat(y ," = ", "$", costStr);
    
    % To make string for pie chart legend
    blank(k) = numStr(1);  
end
%% Makes pie chart with labels and legend 
figure(1); % figure function required to plot more than one figure in a script
pie(blankCost)
grocSumStr = num2str(sum(Table.Cost(grocLocIdx)));
monthName = string(month(datetime(theDate,'InputFormat','uuuu-MM-dd'), 'name'));
yearNum = string(year(datetime(theDate)));
title( "Location Expenditure for " + monthName + " "  +  yearNum + " (" + "$"  + grocSumStr + ")")
legend(blank, "Location",'southoutside')
hold off
%%%%%%%%%%%%%%%%%%%%%%% Items Section %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%% Blank vector to store Item totals
itemBlank = zeros(length(grocLocCats),1);
%% Blank string to store Location and Item concatenated strings
itemMTStr = strings(1, length(grocLocCats));
for k = 1 : length(grocLocCats);
    y = grocLocCats(k);
    locIdx2 = strcmp(Table.Location,y);
    locItNum = sum(Table.ItemCount(locIdx2));
    itemBlank(k) = locItNum;
    itemNumStr = num2str(locItNum);
    itemLegStr = strcat(y, "-",itemNumStr);
    itemMTStr(k)= itemLegStr(1);
end
%% Makes pie chart for Items No.
figure(2); % figure function required to plot more than one figure in a script
pie(itemBlank)
title("Total No. of Items at Grocery Locations" + " " + monthName + " "  +  yearNum);
legend(itemMTStr,"Location", "southoutside")

I think this has to do with how live scripts handle figures. The fix is to remove the (1) and (2) after the figure commands in your function.

% Creating a dummy data set for testing
grocLocCats = ["cat1";"cat2"];
grocLocIdx = 1:2;
theDate = datetime('now');
Cost = [15;25];
ItemCount = [122;34];
Table = table(grocLocCats,Cost,ItemCount,'VariableNames',["Location","Cost","ItemCount"]);
test(Table,grocLocCats,grocLocIdx,theDate)

% Place the code in a function to reproduce the reported use case.
function test(Table,grocLocCats,grocLocIdx,theDate)
%Creates blank string to start compiling location names to make legend
blank = strings(1, length(grocLocCats));

%Creates blank vector for compiling cost numbers
blankCost = zeros(length(grocLocCats), 1);

for k = 1:length(grocLocCats)
    y = grocLocCats(k);
    locIdx = strcmp(Table.Location, y);
    cost = sum(Table.Cost(locIdx));
    blankCost(k) = cost;
    costStr= num2str(cost, '%0.2f');
    numStr = strcat(y ," = ", "$", costStr);
    
    % To make string for pie chart legend
    blank(k) = numStr(1);  
end
%% Makes pie chart with labels and legend 
figure % <----------------------------------------------------------------####### remove (2)
pie(blankCost)
grocSumStr = num2str(sum(Table.Cost(grocLocIdx)));
monthName = string(month(datetime(theDate,'InputFormat','uuuu-MM-dd'), 'name'));
yearNum = string(year(datetime(theDate)));
title( "Location Expenditure for " + monthName + " "  +  yearNum + " (" + "$"  + grocSumStr + ")")
legend(blank, "Location",'southoutside')
hold off
%%%%%%%%%%%%%%%%%%%%%%% Items Section %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%% Blank vector to store Item totals
itemBlank = zeros(length(grocLocCats),1);
%% Blank string to store Location and Item concatenated strings
itemMTStr = strings(1, length(grocLocCats));
for k = 1 : length(grocLocCats);
    y = grocLocCats(k);
    locIdx2 = strcmp(Table.Location,y);
    locItNum = sum(Table.ItemCount(locIdx2));
    itemBlank(k) = locItNum;
    itemNumStr = num2str(locItNum);
    itemLegStr = strcat(y, "-",itemNumStr);
    itemMTStr(k)= itemLegStr(1);
end

Thanks! This fix doesn't seem inituitive though. I would think I would need to distinguish the figures with numbers. I also searched previous answers that actually recommended including the numbers.
