Movies marked as Watched

I have been in search mode looking for new movies to watch and seeing some of the movies that I have watched as being Marked Watch, a bunch of other movies that I have watched and knowing that I have watched by seeing them in my saved list are not marked as being Watch.  It is so bad that I have to take time and remark these movies as Marked Watch once again and then seeing them at a later time as no long marked as Watched.  I haven't noticed any real solutions being offered at this time to put this issue to sleep.
