Profile Sheet : Vertical alignment(MOTIF) got detached from drawing model (do not know the reason)

I have created a MOTIF file, which has both plan and profile information. I created separate name boundaries from my plan and profile and cut the sheets into a different .dgn. 
The MOTIF file reference in each of my profile sheets turned red and do not show the vertical alignment anymore. When I hover over the attachment in the reference dialogue box it says "Model Not Found - [Attached Long Section]".  I checked my motif file and it seems like the name boundaries I created for the profile sheets got deleted. 

Is there a way I can fix this issue, without having to re-cut the profile sheets how can I make the existing profile drawing models to find the MOTIF profile model? 

Thank you for your time.
