dimention error in matlab simulink

Hello Every one.

I have work on some electrical network on matlab simulink and I have faced to Errors such as : "Error in port widths or dimensions. Output port 1 of 'prot/Battery Storage/Two-Quadrant DC//DC Converter/ ' is a one dimensional vector with 1 elements."

Can Some one help me to fix it? Also my matlab version is 2018b.

The Two-Quadrant DC/DC Converter needs two gate signals, one for high side switching device and one for low side switching device. The PWM Generator provides only one gate signal for the high side. The low side signal is obtained using a logic NOT.
