Hi Lorenzo,
Do you have functions with the same name that might be shadowing the actual functions?
You can use in the MATLAB command line, for example
which -all bode
To see files its brings up with the same name. The first file location is the one that will be used. See if the first returned function location looks something like this
C:\Program Files\MATLAB\R2020a\toolbox\control\ctrlobsolete\bode.m
If not there might be another file shadowing this one.
