Battleborn Season Pass Unlock Key Problem

So is there something I am missing or should I get more unlock keys than 2? I got the deluxe edition on Friday (off PSN store) and I have been playing all weekend and was wondering if this is a bug or not. The fact is I only have 2 keys (didn’t use any), I havent unlocked any character just yet and heroes I have locked are: Alani, Beatrix, Kid Ultra, Ernest and Pendles. Should I submit a ticket or is it normal?

Common error. Submitting a ticket here should help
