Double check this:
1. Is your 2 star general within the range of an Army. To check, you the shift key on the army unit to see how far the highlights go.
2. Double check the 2 star general doesn't have a locked unit it (like a garrison). I think that would also stop it.
Footnote - you can also use a 3 star general to be a corps commander if they don't lead an army.
