Error during matrix processing

DimaMog (4)
I have a Function class that contains the union, difference, assignment, and intersection operators (+, -, =, *).
The problem is that I can not output the resulting set (F). Output only F = {}
I think that the error in the cycle of processing vectors by the matrix.

I'm afraid if you don't provide a minimum compilable example you are not likely to get any answer...
