Battlefront Season Pass won't install. Already googled tips. Please help.

I just got a PS4, so I'm not totally familiar with everything.

So, I got the $10 Battlefront with DLCs included, the game downloads, and then there are two separate things that need downloading, one that is the Season Pass. The other download and installs fine (I guess, I don't really remember what it is), but the Season Pass will download and install, but when I go to the game, all the DLCs are inaccessible. The maps packs try to take me to the Store, where it says "Installed". But I can't access them. I've tried multiple different ways of fixing it, including deleting and reinstalling the entire game.

Please help.
