Continuation Tag when a spool ends with a Revit Family

I have recently discovered that a spool continuation tag will not be placed at the end of a spool iso drawing if it ends with a Revit Family. For instance, I had a spool that had a 6" backflow at the end of it and when I generated the sheets for this spool, a continuation tag wasn't placed at the end with the backflow because it is a RFA.
