Save File Issues

 I’m having a multiple issue with the save files attached to my account. First off, I joined back into my account for pvz2 maybe a month ago and it had 7 save files. One of them was a save I commonly played on and was decently far, another was a save I might have started and got a little past the start, but the other five accounts are completely blank and never before started. The issue is that in the save selection it auto selects one of the files that I don’t play on, and no matter how much I play on another save it still selects the other one on load-up. I also can’t rename or delete any of the save files. Second off, my arena is linked between all the saves, as I accidentally loaded one of the wrong saves and played a round in the arena but I realized that I was in the wrong save so I switched over to my main save and the arena was already played in. I think the easiest solution would be to delete the other save files I don’t actively play on.
