CustomPress adds redundant second Tags field

I'm using CustomPress, it seems I have a choice of having 2 tags fields or no tags field at all. The first field is the regular tags, as with any post with tags enabled. The second field seems to be tags specifically for the Photos custom post type.

I'm also using a custom taxonomy, also called photos, so I can have archive pages. Not sure if that has anything to do with it. Please advise, how can I have only 1 field for Tags?
