Missing tracks and orphaned files after importing Engine library into Mixo

Hi everyone,
I’ve run into a big problem while importing my Engine library into Mixo.

My Engine library has around 100,000 tracks, organized in many playlists and sub-playlists.
After the import, a lot of tracks are missing from their playlists.

Example:

• Main playlist: MUSICA DANCE → 200 tracks
• Sub-playlist: TOP → 120 of those tracks
• Sub-sub-playlist: SUPER → 73 of those tracks

After importing into Mixo:

• MUSICA DANCE shows 196 tracks instead of 200
• TOP shows only 4 tracks instead of 120
• SUPER is fine with 73 tracks

So... where did the other tracks go?

When I run Orphaned Tracks Finder, Mixo finds about 1,000 orphaned tracks.
Each one shows the correct playlist path (like MUSICA DANCE/TOP), so it clearly recognizes the playlist reference — but it doesn’t automatically re-assign the track to that playlist.

Right now, the only way is to manually move each orphaned track back into the correct playlist, which is impossible with a large library.

Has anyone else experienced this?
Is there a fix or some way to make Mixo automatically rebuild or re-link those tracks to their original playlists?

Thanks in advance!
