Recording Actual and Remaining Units Against Multiple Resources

  I have a 10 day task dependent activity with 2 resources.  When I apply progress:  Actual Duration, Remaining Duration, Actual Hours, and Remaining Hours; the correct Duration % Complete calculates to 50%. 

The issue lies with the Actual and Remaining Units for each Resource.  The Actual Units are calculated evenly across each resource versus 50% against the Budgeted Units, which also affects the Remaining Units.  Why is this happening, and what can I do to get P6 to calculate the Actual and Remaining Units “correctly”?

Current:

Resource 1   Budgeted Units = 80h   Actual Units = 30h   Remaining Units = 50h

Resource 2   Budgeted Units = 40h   Actual Units = 30h   Remaining Units = 10h
