CustomPress - Custom Field - Required and Validation

Simple question - hopefully with an obvious answer.

I have the latest version of Directory installed.

Within CustomPress I'm adding several custom fields to the 'directory_listing' post type. I am ticking the required field box and including regular expression validation. They are all text fields.

When I add a listing... the fields don't seem to be required... and the validation doesn't work. That is, I can type in garbage and publish no problem.

Am I missing something?
