I'm using the latest validator code and it's forcing me to select an answer for each group of radio buttons, however I have not set them to required="required", so they're optional.

Secondly, when the error message pops up saying to choose an option, once you select it and re-validate, that error message persists whereas other error messages like the ones on a blank required text field, for example, will go away when you enter a value and re-submit.
