Interface functions not showing up in "MyBlueprint"-Panel

My Blueprint implements an Interface, and that Interface has a Function. According to the documentation and all the tutorials I’ve seen the function should show up in the “MyBlueprint”-Panel of the Blueprint Editor, but it doesn’t. How do I fix this?

Found the probmem: I didn’t give the function an output so it was treated as an event. only functions with Outputs Show up as functions in the “MyBlueprint”-Panel
