Customers carrying over from previous shift in QuickBooks Time

Is there a setting that keeps the customer from previous shift for my team? I noticed that the last customer they select carries over to the next day, even if I go in and change it to the proper assigned customer. This is very time consuming to change every employee every day, any help would be much appreciated.

For more context, we recently changed our permissions to have only a few generic options assigned to staff (shop, no customer, unknown) so they aren't viewing customer addresses and other sensitive information. Now, any customer that was previously selected by staff before this switch is carrying over onto every new timesheet they enter. If there is a way to have the job I assign to them carry over instead that would be amazing so I don't have to change it everyday for long term jobs. 

Example: Employee had selected "Customer ABC" as their job for the day when we switched our permissions. I manually switched it to the proper customer "Customer XYZ", but everyday when they clock in it automatically assigns them to "Customer ABC".

Hope this makes sense. Thanks!
