Trying to play local co-op, the Hero for P2 are not loading. Only the Hero for P1 are available.

Both players have activate the Microsoft co-op account. When playing from P1 account, P1 heros are ok and same goes for the second account on the PS4 when logs in her game, her Heros are there and ok but as soon as we try to coop, only the Heros from P1 account will appear. If its my account (main account) that is P1, only my heros are available for both P1 and P2. If we are on my wife account (second account on the PS4), only her heros are available for both P1 and P2.

How can we play again together in local coop on the same PS4 with our respective heros like we use to do before?

Thanks
