Hi guys
Good news. I’ve started testing, debugging and believe to have found and fixed the issue!
Can you please edit the file ‘admin/field-groups.php’ and replace the function ‘check_sync’ with the following: https://gist.github.com/elliotcondon/ebac045330753710e4ce379d036a2185
This should solve the issue of a sub clone field replacing itself with selected fields during sync!
Thanks
Elliot
