XF 2.2 Required custom field not being enforced

[TheLaw]

I have a simple dropdown list that the user is required to make a single selection. Unfortunately this is not being required and users can just blow by it without a selection in the custom field. I am guessing that there is something that I may be missing even though the box is checked to be required?

This works except it's different than prefixes, where the requirement setting is actually in the node itself. Makes sense. Moving on...
