"Play Other Songs In Album" function not working

I have Play Other Songs In Album or Directoryenabled for my players, which include both Touch and piCoreplayers. After a single track is selected and played, it should continue to play the remaining tracks, but the tracks stop. If I enable Don't Stop the Music, then random tracks will load and play as expected, but not the remaining tracks in the selected album.
LMS is 8.1.0 - 1608700893 @ Wed Dec 23 on a piCoreplayer server and also on a Vortexbox, both showing the same behavior.

I can't recall if this was happening on my previous 7.9 version. Any idea's?

Edit: The server log shows this...

Edit 2: If I open an album in ipeng and select any song, it will be followed by the next song as expected. The behavior above happens when using LMS in a browser on my PC, which I happened to be doing today. I almost always use ipeng, so this won't really be a problem, but I assume tracks should continue to play when started from the browser page?
