I figured out why it cannot see my league folder in my ootp21\saved games folder....
because it moved the default data folder....

If you go to file, settings, then export, then the custom data path (*), somehow this got changed to within my other leagues folder.
So it set that path to: Documents\Out of the Park Developments\OOTP Baseball 21\saved_games\NDL.lg\saved_games

And this should have be:
Documents\Out of the Park Developments\OOTP Baseball 21\

I adjusted it and things are good there.
