I noticed something wrong for the save...

There is a "save" icon at the bottom right hand corner when you finish a level or pick up a collectible, it's normal. However, after you finish the level, if go back all the way to the very first title screen, there is also a "save" icon appears... I did that and I noticed it would reset my save to a new one...

Luckily I had the old save in the cloud after I deleted the save in console.
My suggestions is after you finish the level, and see the save done completely, just force quit the game in the open world screen,
DON'T go back to the first title screen.
Perhaps only me had that problem, please prove me if I am wrong...I am using Xbox One X.
