Computed or Calculated values turn off other SUM values

Views 6.x-3.x-dev
Views Calc 6.x-3.x-dev
Computed Field 6.x-1.0-beta5

The process I am using is to SUM the field values in each column.
Training | Vol Service | Vol Travel

All three fields are in the same content_type and SUM is displayed correctly until I add a value for Total Volunteer Hrs.

I can calculate (Service + Travel = Total Hrs) using the CCK Computed Field or the ViewsCalc Field option. That part works.

When I add the Total Hrs value to the display and check mark the SUM option, the SUM for the Total Hrs will display; however, the SUM for Service and Travel will no longer display.

The Exported View and the screenshots of the display with and without the computed/calculated value is attached.

I made this example simple; but I would like to include special thanks to the module Developer(s) for the hard work it must have taken to get Views_Calc to handle Relationships. It has greatly improved my use of the module.
