"Playing next" queue auto-generating and in some mystery order (NOT shuffle)

System: Windows 10

App: Apple Music 1.5.4.79 (1.1284.20225.0)

Okay, this is either new behavior - or it's "just me" and I can't find anybody referencing it yet, possibly because so few people use this app?

I have filed a bug report on this as well, but... Anybody know what's going on here? Before the latest version (installed yesterday) I was able to click on any song in my library, and have it, you know... Play every subsequent song in order, and I've never needed a queue before. But today - well... You can see the screenshot below.

As you can see, I have selected the song "Rocket Collecting" - which then generates this whole "Playing Next" queue, which I did not select, and decides that my next song should be another one from the album, followed by about half the Transformers soundtrack, then random other stuff, and finally about half the Spawn soundtrack.

When, instead, it should play some more artists that start with M. This has worked fine for years. It worked fine two days ago. And today... Whatever this is. NOTE: This is not a "shuffle" situation, I already checked that, and it behaves differently.

I can't find any reference to this new behavior, and I can find no way to turn off that queue. Anybody know what's up?
