Missing metadata on videos placed on a USB-disc connected to Synology NAS

[lhsoefren 1]

For a long time I have used a USB disk for some of my video movies connected to my Synology Disk.
I was previously able to use the "Identify" function to find metadata for movies based on IMDb Id, TheMovieDb Id or TheTVDB Id. When a movie is placed on the USB disk, I can now only select "Title" or "Year", which is why I can no longer get metadata.
For movies placed directly on the NAS, this function is still available. How do I get metadata for movies on the USB disk - it has worked before?

Solved  - In "Settings" I have selected "Library" and then selected my file library on the USB disk. Under "Movie Image Fetchers" I have selected the databases that I want to be able to select. Then the options appeared under "Identify"
