Manager keeps editing my time sheet

Is this a normal thing? It’s happened multiple times already. The last site I worked at it never happened, but now it’s an issue. I got mid shift VTO for 1:40am and saw it right at 1:40am so by the time I cleaned up and clocked out it was 1:43am. I just checked right now and it says a manager made an edit and my out time was 1:32am.

I didn’t see any of my regular manager or PAs on this shift so I have no clue who did it.

Do yall know why they would do that?
