Two fields set as required, but people are not being required to complete them
 

In my Profile fields I have two additional fields -- one is a spambot prevention profile field and the other a location profile field. I have them both set to Required > yes on registration & profile updating.

Yet, people are registering without filling those two field out -- leaving them blank.

What could be the cause of this?

Here's a screen capture of the setup for the Location field:
