I think you’re having the same problem I just reported through a support ticket.
The problem is how GF passes checkbox (and probably select) multiple values to AC.
AC needs checkbox multiple values to be wrapped and, more importantly, separated by
|| instead of commas. For example,
||Facebook||Twitter||Google||, but GF is sending
Facebook,Twitter,Google. Thus, AC is reading that as a single value instead of multiples.
“Contains” options in searches and automation will see “Facebook” from that, but your contact won’t look correct in your list and they won’t be able to uncheck options.
So we need either Gravity Forms to fix this bug in the AC add-on, or we might need to implement custom code (ugh!) to fix the bad data Gravity Forms is trying to send to AC.
