Budget Builder issues with Baseline Override

I’ve added the Budget Builder worksheet and followed the steps. I have removed one time line items from the previous year. But when I get to the “Set Your Baseline Monthly Budgets” step it doesn’t work quite like the instructions.

I have a minimized budget based on prior year actual, but if I enter a baseline override in to AW it doesn’t override the minimized prior-year actuals but instead adds them. For example, if I minized December by 500 and then set my average to $50 per month, the value for December is now -$450 instead of $50.
