What Takes Priority?

As any editors know, there's currently a bug for creator check boxes, allowing you to only check one designation for each creator. My question is which job takes priority? I'm working on converting a bunch of trades that are grouped together as series into individual volumes and I can only choose one title for each creator. 

Since the bug started I choose writer over artist. If an artist does the interior art and the cover, I pick artist as a priority.

Since colorist is an artist too I'll just choose that if they did line work and coloring.

Hopefully it gets fixed soon but I wouldn't hold our breaths.
