When updating (a part of) my database, all new files get a 5-star-rating. None of the files have a rating stored in the database.
Which exact version are you using?
If you are using a version released later than the most recent official beta, please open a support ticket for this since that will require special handling.
Thanks. Be sure to include one or a few sample files which can be used during reproduction. I did some sample tests myself and it did not resulted in any 5-star ratings..
Issue located and corrected for the upcoming build.
