Battlefront 2015 dlc trouble

I know this game is super old but I would like to go back in and play a bit of the dlc content if possible. I bought the season pass way back when in 2017 or 18 but everything is locked and to download, the ps store wants me to buy each dlc individually for 14.99. Would like some guidance if possible, I know im on the right ea account and psn. Wanna play but don’t wanna pay 60$ for something I should already own. Any info is helpful, thanks
