Ability Card and Boost Cards Not Working

So my heavy is level 80 and when I used to play the game I had all the ability and boost cards unlocked but I got back on the game yesterday and now it says I don’t meet the level requirements for the cards. Does anyone know what to do? I want to start playing the game again but every match my characters are all reset to level 1 and I don’t know how to fix it. (This is on Star Wars Battlefront 2)
