ARK Dev Kit UI/Inventory problems

I have a problem when it comes to using the right UI for my mod, I can’t find out where it is supposed to go i have checked every BP. Basicly i have made a mod that uses an altered version of the smithy, but when i place my “smithy” and open the UI it opens the vanilla smithy UI instead of my altered UI.

Anyone know how i can fix this?

Do you still need help with this or could the guys in your other post help you?

I got what i needed from the other guys.
