some parameters are None in foundation branch

[jungsdao]

Describe the bug
When I train model with foundation model branch, some of inherited parameters are given as None in the train logfile.
For example, num_channels=None and max_L=None.
I guess these parameters are from foundation model but not properly displayed.
folowing is part of training logfile.
