I spoke to one of the UI devs about it actually (forgot to follow up on it). It's a known issue, but they weren't able to fix it before the release. It's intended to be at return index #14, and the boolean is (iirc) castByPlayerCharacter.
Should be fixed in a future patch, but until then it's being pushed onto the end of the stack. Just wrap returns #14-17 in a "tonumber(<var>) or 0" until then.
