In my case I had duplicates for several different files in one folder, not 10 copies of one file. I resolved the problem by renaming files and deleting duplicates. I decided not to report that issue because I thought I have unintentionally done something crazy. Btw, they likely occured also after power loss. Regards, Maxim Fomin
