Sometimes it happens the conditions for a cloneable group is not working anymore.
I'm forced to delete this group with all its content a recreate the group.
Following the documentation https://docs.metabox.io/extensions/meta-box-conditional-logic/#using-with-group
if the first group field Content Group is a cloneable field, the conditional logic will run inside the clone and its subfields, search for a similar ID and apply the logic.
To fix the issue, you can try to use another field ID for the subfield in the group_titles field (not including "mode").
