Can't download a game?

Moin, so I deleted a game yesterday I want to download it again but in my library "is" instead of "downloading" this download bar and when I go on it it says "start" and as soon as I confirm the message "application not found, would you like to look for it in the store "and when I press yes, the store says exactly the same

So how do I get the game back?

You have to wait first after you have pressed "Download"

Who can read has a clear advantage, there's no download anywhere there's only the download bar as if it were loading but nothing happens and that's why I can't press download because it doesn't exist
