The COUNTRY field->edit updates just fine, but other SELECTOR fields do not. Create a new selector-type fiield. edit an existing profile and try to select any option other than the first one, and save the changes The database does update, but the edit field does not - it still shows the first value. An if you save it again, your option choice is gone, and the first option is saved back to the database.
What happened to the "Select it" choice that was the first item in v6.16?
