I added a new Category by adding to the Collections list in the Tags menu. I then added the new tag to 72 movies. Only the first 7 movies were listed in the newly created Category. I verified that all of the movies got the new Tag. So I decided to backtrack. I removed the new Tag from all of the movies. No change. I removed the Tag. No change. I deleted the new Tag. No change. Now i have 7 movies populating a Category that have no Tags to do so. I would like to delete the Category and start over. What did I do wrong?
I removed the new Tag from all of the Movies and deleted the new Tag and ran the Optimize Database and it removed the new Category. Awesome!
I added the new Tag to one movie, which recreated the new Tag, and the 7 movies that were in the Category returned. The movie that i just added is not in the newly returned Category. The movies that are in the newly recreated Category do not have the new Tag. Strange.
A Category is actually a Genre.
It has nothing to do with collections.
That’s the way to do it if you want immediate results. Otherwise this is done automatically during the maintenance period.
After you edited a movie and changed one of the fields, the orange lock on that field is automatically engaged. Take a look again and check if the “locked” status of the Genre field is as expected.
It can’t hurt either to verify the health of your database file:
Or inspect them yourself. Take a look at the Plex Media Server.log file and seek for messages about database corrupt or malformed.
If you find these, you may have to repair your database. https://support.plex.tv/articles/repair-a-corrupted-database/
