Submitting actor credit where "Himself - Host" is one of multiple roles puts all roles in "Self" category.

For example, an actor has multiple roles in a variety show where they play themselves as the host and several sketch comedy characters, so I enter the credit using the multiple role / rule as:

Himself - Host/Police Officer/Angry Baker

However, on the actor's IMDb page the entire entry shows up in "Self" only, when it should show up in "Self" and "Actor". How do I fix this?
