When I sped up subscription and downloader load time a couple weeks ago, I messed something up with local import folders that caused them to one-time re-check of any files they were remembering (i.e. entries where you said 'leave alone, do not reattempt'). It resulted in some wasted work and an UI bug. Thank you for the reports about this. I have fixed the problem, and any duplicate/redundant import objects should be removed on update. Let me know if you have any more trouble!
