Bill,
If you are a Manager and have access to Approve, you can view Approval Module and see all submitted time by the users. You are most likely looking at the Timesheet Module that shows timesheets for all Tasks whether time has been put in or not. You can still do approvals from Timesheet but will need to Navigate to the Tasks that have time entered. There is also a 'Change User' button on the toolbar ribbon that allows you to choose any user in the system to review their time.
Sincerely,
Boris
