Do you have your transcription button set to a particular country or cemetery? I just have my language set to English (and even with that I get some non-english stones). I'm not having your issues at all (but I have had this in the past). There are many pictures in the US cemeteries that are hard to read. That comes with the territory. Some people take lousy pictures and don't review them before they upload, nor do they remove them if reported. If the pictures truly aren't legible, you should report them and they will eventually be removed from the que.
