Why cant i play certain maps on battlefront 2

Product: Star Wars Battlefront II
Platform:Sony Playstation 4
I want to talk about something you don't mention above:
How accessible is the current experience? It's overall fine
Summarize what in the product is difficult to use. I cant play certain maps on the battlefront 2 and i really want to know how i can get to play them
How is this making it more difficult? Its not making the game difficult i just want to play all the maps
How can we reproduce this experience? Allow access for these maps or tell me how i can play these maps

‌

I just wanna understand how to play these maps because i really enjoy this game and its overall really good i just wanna know how to play these maps
