How to keep image labels after combining two datastores?

Hello, I have two sets of 58 images each which I have to feed as input to a multiple-input network.

To do so, I first read each of the sets onto a different Image Datastore, as shown on the images

Reading the first dataset:

And then, the second dataset:

Then I merge the two datastores by using 'combine'. However, according to the documentation available here, I should be reading a three-column cell array, wherein the third column would be the labels. I get only two columns when reading though:

If I try to give this combined dataset as input to my network (which has two inputs and one output) I get the following error message:

>> net = trainNetwork(imdsCombined,lgraph_1,options);

Error using trainNetwork (line 170)

Invalid training data for multiple-input network. For a network with 2 inputs and 1 output, the datastore read function must

return an M-by-3 cell array, but it returns an M-by-2 cell array.

I am using R2019b by the way.

So, is there a way to insert the labels column onto the cell arrays read from the image datastore? Or is there something else I need to do?

Thanks for all the help.
