Weird. I checked some subset of the above. All of them show up as part of at least one bundle I own, even those I had never clicked before. https://brokenrules.itch.io/and-yet-it-moves shows up as part of the Ukraine bundle for me, but https://draknek.itch.io/sokobond does not.

And neither of those show up as the Ukraine bundle (which I also own) for me, they only indicate the World Land Trust Bundle. Whereas other games do include the Ukraine one. And some include all bundles. The bundle-checking-and-displaying subsystem seems to have errors in it, leading to omissions that don't follow a pattern I can identify.
