FAQ: Why Am I Getting a Warning for Incomplete Expenses?
Some of the expenses warnings will trigger when certain categories are below typical spending, like housing repairs/maintenance, vehicle replacement etc, but this isn't a critical issue as long as you're confident your spending is accurate.
Other warnings are specific to categories like "Food/Cleaning/Staples", "Phone, Cable, Internet", "Restaurants", "Entertainment", "Clothing", "Personal Care". If any of these are $0, either in current spending or in future spending, then there is a warning because there is typically an expense expected in these categories.
As long as you feel confident about your spending your can safely ignore these warnings.
