Katana Proficiency BUG (monk)

[Harry Gold Tongue]

Hello guys,

I have an issue with my katana weapon.

I have monk levels and monk has a feat - proficiency with katana.

But when I put katana in the weapon slot - it has penalties like I didn't have the proficiency with her. Though when I rest with katana in my hands - it has no penalties and works as intended.

The problem is - every time I take katana off and then reequip it - it has penalties (-8) again.

It's clearly a bug cause monk has a feat - proficiency with katana and there shouldn't be any penalties.

Hope this issue can be solved...
