This doesn't actually affect the budget (it shows $0.00 for this period's total) but rather the little tooltip on the category. What this is showing is me paying $9.99 a month for Uber One and then getting a $9.99 statement credit from my credit card to cover it a few days later. If I look at the Ride Share category in Budget the tooltip doesn't seem to be calculating one of those as a negative number because it warns me to pad my budget by $19.98 rather than recognizing these two items zero out.
