What is causing this issue?

The wrong date for Business Day is due to not closing the drawer correctly.

How do I resolve this issue?

Select Manager in the upper right corner of the Order Entry screen.
Choose End of Day from the drop-down list.
Ensure all tips are finalized and print an X-Report. This allows you to have a record of the sales you performed from the previous day.
Select Close Register and select Yes when prompted.
Press Back in the upper left to return to the Order Entry screen.
The system will prompt you for "Start of Day: How much are you starting off with?".
Tap on the calendar next to the date, and select the appropriate date.
Select Save to change the date in the upper right corner.
