Ok, that helps.
The name 'Other SVC Charge' in that section is a tracking group (most likely). If not, we may be in trouble.
Go the POSconfig>System>Tracking Groups
Can you find a line item in the list called 'Other SVC Charge'? If so, is it linked to a specific SVC charge or a group? Send a screen shot if needed. My money is on a group.
Once we know what this line is reporting, we can remove discounts from it. If it is a group, then there are some/all/most discount assigned to that group#. Go to each discount and remove that group# from the discount. There is a field to put the group# (not sure the name). Make sure that the discount is tracked somewhere, go back to tracking groups and verify the discount is either in another group# or linked directly to a tracking line. Otherwise, the total discounts in the middle 3 columns will not match the top boxes (the top boxes are always right, the middle is changeable).
