System is overriding the to date of the timesheet when uploading

hello,

I am loading timesheet for a week. The total working hours are 40hrs, From date - to date = 25-Sep-2023 to 29-Sep-2023.

However after loading we have notice that the to date has changed completely, not the same as we have loaded.

Kindly advice how to make the system read our timesheet correctly.
