Overflow leader/trailer displaying as leader/trailer correctly but also displaying outside repeater

When creating a new overflow leader and trailer, a subform is created and added to the hierarchy.  I've correctly assigned the repeating subform to the overflow leader subform and the overflow trailer subform.  When rendering, it works for the repeating subform but the subform's text also appears outside the repeating subform due to the fact it is still a subform with text.  There is nothing that I can find in the leader/trailer subform telling Adobe to not display it outside of being a leader/trailer to the repeating subform it was assigned. ???
