We've discovered several instances of student enrollments hanging around in crosslisted courses after they have been removed. This only appears to happen in crosslisted courses. We are merging our crosslists and using an XML folder. bannerxmlfoldercomp and unenrolmember are enabled, droppercentlimit is at 10% and I've manually verified that the users are not listed as enrolled in the XML. We're using LMB 2.1.7.

I will send the logs to you directly.
