Cached songs missing while syncing

Issue description:

I have two libraries added. One is my server local host and the second is the same server but via Tailscale. The Tailscale one is the one I use the most, but lately I have noticed that whenever it starts to sync some of the songs from fully cached albums are missing. I know that it only breakes during sync as I have the same albums cached from the local host, and those are fully showing up and after the sync they also paper on the second instance. I very well may be something that I have misconfigured in the settings, but it seems to be unintentional. Cheers!

Additional information:

 
The first SS shows the album from the Tailscale instance, whist the second one is from the local instance. Both have the same album selected and are fully cached, but the Tailscale instance is being synced.

 

Reproduction steps:

 
It happens sporadically and to random songs, so it’s hard to reproduce, but the process is pretty self-explanatory.
