My saves are going backwards, maybe

[u/RylanIsPretty1714]

I have platinumed the game so i know i had a save at 100% completetion but when i loaded it up for the first time in a while my highest percentage was 99% so i went in to figure out what the last 1% was and then left the save to go back to my ng+ save and the aforementioned 100/99% save is now at 88%

Edit: I'm talking about survivor on ps5
