I purchased the Bundle for Racial Justice and Equality yesterday.  The first game I downloaded shows in my library as an owned game and gives me the option to install, while the next couple of games only show me the option to "buy" and not install the games.  I only have one user name/account with itch.io, so it is not an account incompatibility issue as far as I can tell.

Any ideas on how to fix?

Never mind, it looks like the status of the games updated.  If anyone else has this question, it took about 15 minutes after initial installation before the games showed in the correct status.

Almost the same problem, with the exception of overland, all the games in the bundle won't show as owned (i can't download them on the game page)

me too.

and my list is empty

I'm also having this issue. I've went through all 55 pages of games, added some to collections that I want to try first. Of the 19 games I've done that to, only two show as installable (both on the website and in the app), but that's because one is already free and the other is name your own price.

Anyone figure this out? I'm still having this trouble.

As far as I know, you need to download directly from the bundle's download page and not the game's page.
