CC Merged Corrupted File ERROR??

Hi guys so I got an error when trying to unmerge files (previously merged with s4s). They are preset items and im unable to unmerge them because apparently something within the file is corrupt?? Im not sure what to do. I'm able to open the game just fine with them, just insure due to the error.

Error in question:
