Options field and required if won't validate

[landitus]

I think this could be a bug. I'm using an Options field to create an array of radio fields. This field is required. Each option activates a conditional field and this works perfectly. I added a required if condition to this conditional fields, on a template level, and this is displayed correctly with the red *. But the fields are not validated and the page saves nonetheless. I figured since the red asterisk is on, I've configured the fields conditions correctly, right?
