TimeTrex Time and Attendance

Here are the attachments showing what I am seeing, from a previous week. The calculations on the timesheet are not even computed correctly.

Why do pay stubs show more hours than the timesheet every week?

Example: last week the employees timesheet shows 37.35 hours, the pay stub after running payroll shows hours at 37.58.

I looked back at prior weeks, the system has been doing this since we started using it in June.
