Old data still present in backup file

Steps to reproduce

Not sure how to reproduce or if it's still happening.
I've had the same backup file for a long time and i have A LOT of movies and series saved, which I've manually migrated to newer extensions after the old ones stopped working.

Now when i migrated some more movies i noticed that i constantly got asked to replace movies qnd series that weren't even in any watch categories and literally said "none" next to the title

If i open the backup file in a text editor im able to find titles i don't have saved, from extensions i haven't had installed in a very long time, but im not really sure what im able to remove so would it be possible for you guys to add something that will purge titles that are saved to the category "none" or where the category is missing?

Second problem with old data.

I've changed the download folder twice and for some reason every time i restart cloudstream it re-creates a few empty folders in my old download location of titles that aren't even in the download tab and haven't been for a long time, so I'm not really sure how to remove these from my backup file.

Is there something you guys can do to clear out old downloads that aren't visible in the app?
I have a few downloads but i would happily remove them if it would help getting rid of those "hidden" download entries.

So is this salvageable or am i screwed and have to start over and re-add all movies and series again?

No source file, test, or entry point is named. Start by reproducing the backup and download-folder behavior described for version 4.3.2, then trace how entries with a missing or "none" category and old downloads are retained; done means stale entries can be removed without losing current saved media.
