Parent task roll up has incorrect values based upon lower levels of project budget

As shown in the screenshot below, we would expect that the two values in the red boxes are $0 based upon the task and expenditure type combination containing a budget of zero. What would cause the top task budget to differ from the sum of the lower line level budget?

We did noticed that the values seem to be pulling from Display = Planning Resource Breakdown Structure versus Display = Task Structure. How could these how gotten out of alignment and what do you suggest to ensure that they remain aligned?
