Overflow leaders not working suddenly in my dynamic form

[Joshmon2003]

I have been using a overflow leader on my form for years.  All of a sudden it stopped working a few months ago.  If I start deleting subforms I can eventually get it to work again but I am unable to track down exacly what subform is causing this issue.  It seems like something is corrupt. 

Does anyone have any tips?

Thanks,

Josh

I found this error that is related to this in the Log:

"The SOM expression 'OF_Form152' referenced on the node 'xfa[0].template[0].form1[0].forms[0].FFForm[0].FFForm151[0].Frames[0].dynFF[0].#break[0]' cannot be resolved.  The form may not render correctly on older clients.
PDF generated successfully."

OF_Form152 is my over flow subform.
