Using MB Builder, I have a user meta field group with a Checkbox List with ID commitment and one of the options is pre_event:Pre-event build.
I then have a Select field with ID pre_event_arrival and several days as options. Under Conditional Logic in the Advanced tab, I have it set to Visible when All conditions match and my one condition is commitment [OPERATOR] [VALUE].
I have tried =, contain, in, or match in the [OPERATOR] spot combined with pre-event, Pre-event build, or pre_event:Pre-event build in the [VALUE] spot.
Yet when I go to a page where the field group is displayed as a form using the mb_user_profile_info shortcode, the Select field always shows up no matter how I set the conditional logic.
