Thanks for posting in the Community! If the hours or figures on the pay run are doubled up, we'll need the hours entered on the timesheet and your employee's Pay Run Default settings.
To check the hours on the approved timesheet
Go to Employees tab.
On Manage Employees drop-down menu, select Approve Timesheets.
Check if the details including pay period, employees, hours and amount are correct.
Once done, let's go and check employee's Pay Run Default settings.
Go to Employees tab.
Select an employee.
Click on Pay Run Defaults.
If Use timesheet to submit all time worked is selected, make sure you've unticked Pay these earnings by default in a pay run.
Select Save.
Then open the pay run and click on employee to expand details. Click Actions and the Recalculate. Furthermore, you can delete the pay run and create a new one to apply the changes made on the employee settings.
