Marketplace without some content

That’s strange. I have downloaded a while ago some of the free content by epic. Shooter game and Blueprint office too. But now I don’t see them in marketplace tab. I don’t think it should be that way so what’s the problem?
For example, I can’t upgrade shooter game to ue 4.6 because there’s no page for it in marketplace. So what should I do?
upd. I don’t see content examples as well. Some of other pages too.

Oh, it’s in the learn tab.
