Beginning with a blank timecard or day, uncheck the Auto Calculate button.

Next, let’s enter a pair of punches for our selected day (with no previous punches). We’ll use 6:00pm and 6:00am for our example.  The employee’s schedule is set up to match this-so today they arrived precisely on time and left on time.  Notice that the times get reversed immediately – this is normal even without automatic calculation.

Click on the AM time (it’s on the top now) and click Next Day.

Now you can click to Recalculate Now.  The correct time should calculate and display.
