Save files just disappeared? (xbox)

Hi! Does anyone know what could've possibly happened to my saved files?

I got about 16 hours in on save file one before I found out my game was bugged, started another one and got just over a day in I think, but now neither are appearing?

2nd photo is just proof I've actually played the game. 3rd photo is my saved data on the manage apps section.

Before you ask, yes I am sure I didn't delete them myself, I haven't deleted the game since I installed it about a week ago.

Im not super far in so it's not exactly world ending if I have to restart the game once more but I am genuinely just confused as to where my files have disappeared to, and a little annoyed.

Is this an anomaly?
