smart playlist doesn't show all tracks

So, here's the situation:

I collect all my favorite songs from each weeks New Music Mix and put them in a playlist by each year. Back when i started this, i made a Smart Playlist to collect all playlists in one big one. (This to further filter out by play count, liked, etc..) I edit the rules to add each years corresponding playlist (see screenshot below).

These seven playlists combined have a total of 2.334 tracks, but this Smart Playlist only shows 1.208 of them...!

I checked, created a new Smart Playlist and added 2021 and 2022 (757 tracks) but only 5 tracks appear.

All the tracks in the playlists are in the cloud of Apple Music and only a hand full are "No Longer Available".

Can anybody help me understand and fix why the Smart Playlists i create wont see half of the tracks in the playlists i add?

Any help is much appreciated!

TLDR; I want to combine multiple playlists in to one Smart Playlist (all Apple Music cloud tracks) but almost half of the tracks aren't added.
