I put a point into her proficiency Ninjato/wakizashi/scimitar upon lvl up...

And just picked up my first Wakizashi weapon... and she cant wield it! Even though I put a point into it!!!

On top of that, the item the description says that Druids cant use those weapons...

If Druids cant use those weapon why is the game letting you put a Proficiency point on them!?

Is there a way to fix this or at least undo that point unto something else.

Seems like a HUGE OVERSIGHT by the developers.
