It seems to be a known issue:

No permanent fix found (yet) - seems to be a Finder issue. Annoying, but not not critical. Jon, perhaps filing a bug report, as one of the posters in the Apple discussion thread has done might spur Apple on to fix it. I still haven't installed El Capitan so can't speak from personal experience, but I'll check on this once I do get around to updating all my Macs.
