PES squad not saving (PS4)

When I try to edit a team’s game plan in Pro Evolution Soccer (PES) 2020 on PS4, it just reverts back to the original squad when I actually be the team in a local match. For example, I added a few players to the team Chelsea FC and I saved the data. But when I go to local match and select the team, the game plan just went back to how it was before I edited it. Can someone please help?
