one employee not showing up on quickbooks time kiosk.

Thanks for sharing your issue with us, Selkirksmx.

You may not have selected the specific employee, resulting in not showing on the QuickBooks Time Kiosk. I'll be sure to help you get this fixed. 

Let's confirm that the employee is added to the kiosk preferences by choosing the employee. You can follow these steps:

1. In Time Kiosk Preferences, select the kiosk name to open the preferences. 
2. If needed, update the kiosk name. 
   
3. To limit which users can clock in/out on this kiosk, under Team Members, select all team members and make your selections. 
   
4. Ensure to tick the box for the employee not showing on the QB Time kiosk.
5. Tap OK.
