Records that have changed for some reason.

[huhu575]

The time measured yesterday had changed today.
The 25305th measurement on the CS timer showed 7.03 seconds yesterday and was photographed as proof, but when I looked at it on the CS timer today, it had changed to 12.37 seconds.
The multiple times before that are also incorrect and strange.
I did not do any import, export, or any other operations.
Does anyone else have a similar phenomenon?
Please let me know if there is a solution.
