Foundations Monthly Budget Available balance not accurate

I am using the foundation’s monthly budget sheet and the available balance appears to be adding instead of subtracting the actual from the budgeted amount even though the actual shows a negative entry. Any thoughts on how to correct this? Example below:


Check your Categories Sheet to see how you set the budget amount. Each Category will be labeled as expense or income, and the budget numbers in the monthly columns should all be positive numbers - Tiller will adjust based on the Expense/Income designation.
