Hello. Thank you for contacting the Toolset support.
I would like to know first your relationship depth - do you have one to many relationships or you have nested relationship like Country -> State -> City?
Can you please share problem URL and access details and what field you want to display from which relationship at where exactly?
*** Please make a FULL BACKUP of your database and website.***
I would also eventually need to request temporary access (WP-Admin and FTP) to your site. Preferably to a test site where the problem has been replicated if possible in order to be of better help and check if some configurations might need to be changed.
I have set the next reply to private which means only you and I have access to it.
