For what it's worth, this is happening to me as well. Only affects certain sources--Massachusetts town records is a big one for me. I'm using the Mac version of FTM. I can go onto ancestry.com and access and save the source, then sync to FTM. Other sources work fine in FTM. FTM and all my other software is current.
The records that I can't clip appear to be Massachusetts records that have recently appeared at at ancestry.com. This only started happening within the past week.
