This didn’t fix it for me as I already had the instruction column and I don’t have the ‘save_as_cf’ => $field[‘save_as_cf’], in my ACF code.
This plugin started great, but now I’m just frustrated as the fields in my group gets deleted as soon as I try to edit the group.
This is a major bug. I don’t dare to even click the menu link on the live site.
No other solution to this yet?
