No option to download titanfall 2

I bought titanfall 2 back in 2016, and after my friends bought it on steam I thought I would have to buy it on steam as well to play with them. After learning that it runs through origin on the steam version, i refunded it thinking it would be redundant to own both. At first everything was fine, but now Origin won't let me install the game to play it; on the titanfall 2 library page the settings button doesn't include an option to install and the play button has been replaced with a details button that does nothing when i click it. I've cleared my cache and checked my antivirus and firewall and everything, but it still won't let me install the game. Please help?
