Herbs & Potions BG1 Tutu, Proficiency Type Options

[Alboy]

Hi

Only second post, so bare with me.
When playing BG1 Tutu with Herbs & Potions installed I get Proficiency Type errors, they are:

Staff in BG1 Tutu is Staff but when Staff has fire or posion added it becomes Blunt Weapons.

Dagger in BG1 Tutu is Dagger but when Dagger has fire or poison added it becomes Small Sword.

I believe the Proficiency Type is being changed back to the original BG1 Proficiency Type.

Is there any way to enable Tutu's Proficiency Type as this becomes very confusing as to what is actually being used.

Thanks in advance
Alan
