Which version of MATLAB and Statistics Toolbox are you using?

What do you see when you type:

which -all gmdistribution

which -all fit

I want to make sure that there's no other gmdistribution class that's taking
precedence over the one included in Statistics Toolbox.

This is not the display I expected, which makes me even more suspicious that
you have a gmdistribution function that's taking precedence over the
Statistics Toolbox one or have modified the gmdistribution files in the
Toolbox or that your installation of Statistics Toolbox is incomplete or
