I "think" you need to use Save As and save a copy of the federal, then use that copy for the second 568.

Im guessing there will be some issues getting both 568s to EF you may have to Efile one of them, then once its acknowledged, you uncheck the EF boxes on it and Efile the second one (to avoid the duplicate SSN message in the EFCenter)

I used to just paper file the 568s when there was one than one per SSN.
