In the Marketplace, in some packages, the button "Create this world!" does not appear

In the first photo, it appears that you are downloading the map, but when I click to see the map page, there is no button in the place it should have (the other three photos). This bug has been here for a few days, or even weeks (I don't remember), and this is bad because I can't download or create any of these maps to play.

Edit: The images are in Portuguese, translation of the words: 

Baixando – Downloading

(I think I don't need to translate any more words, if you need, let me know in the comments)
