Some places say there is, some not. Which one is it?

There's a problem.

I'm using a 'tactical' BWP assembly, currently in the BGI campaingn. I want to dual class Imoen into a mage. But, after choosing to dual class and picking a weapon proficiency, I see the window that should let me pick learned spells; only, instead of level 1, it's somehow "level 10" and it's empty; there's nothing to pick and I can't bypass that window. I don't know where this comes from.

Is there a way to edit in a dual class for a character? I can't find that option in Shadowkeeper, if it exists; only multiclass.
