Currently if you have localization enabled you might end up with movie data not being available in your language. Instead it gets the english version. Unfortunately this ends up with you having multiple categories of the same kind, but named differently.
For instance i both have “Sci-fi” and “Science Fiction” as categories, although they are the same thing!
In general i have all categories twice as my library grows!
Would be nice if you could merge categories together, as well as apply a future rule for future movies which cant be matched with a localized version, so they still end up in the same category regardless.
