Merging duplicate albums

[TheHvidsten]

I have a music library with the following folder structure:

Code:

/music
    /TRON Legacy - Daft Punk
        /CD1
            01-Track.flac
            02-Track.flac
        /CD2
            01-Track.flac
            02-Track.flac
        /Bonus
            01-Track.flac
            02-Track.flac

This is imported as three separate albums, as can be seen in the screenshot.
I have not enabled "MusicBrainz" so none of them have a link to it.
All the files have identical "Album" and "Album Artist" tags, and they are correctly numbered with regards to track number and disc number (bonus is disc 3).
I have many other albums that follow the same structure that is imported correctly, but this refuses to be correct.

Is there any way to fix this?

EDIT: I just deleted the config and cache folders so that everything is as clean as possible. Importing everything again and the same issue occurs.

The file's metadata must not be correct. Use a program like mp3tag to check if everything has the same values.

I've already checked with mp3tag. Album name is identical on all the files. I've also set the name multiple times to ensure they are identical, but still Jellyfin refuses to see them as one album.

Does it have Disk Number set up? Also, when you change metadata fields you need to do a refresh with replace all metadata option.

The disc numbers and track numbers are set up correctly (see attachment).

The three albums are split by disc number, though:
The first one is disc 1 (album doesn't say "disc 1")
The second one is dics 2 (album also says "disc 2")
the third one is disc 3 (album also says "disc 3)

When I updated the tags and refreshed the album I always chose to "replace all metadata".
