Why don't sub-categories roll-up properly?

KTPhoenix

This is a current budget report. The roll-up for Tax incorrectly sums to 18,618.28; it should only show 1683.72. Yes, I've chose to exclude some sub-categories from the report but for some reason they still appear in the roll-up. Chosing to exclude the categories from the report should exclude them from the roll-up otherwise the report is inaccurate and misleading and could lead to bad decisions. How do I fix this?
