On the Overview page, the Budget Breakdown displays the Available amount as $0.00 for standalone categories and subcategories with same-category rollovers enabled, when setting a date range of more than one period (ie. annual, or Jan 1st, 2026 to March 31st, 2026).

For category groups, the subcategory displays $0.00, while the Available amount at the category group level is doubled (i.e. If the Available amount is $16,000 it will show $32,000).

Also, in the tooltip when hovering on the Available amount, "This period you budgeted" only displays the amount budgeted in the last budgeting period within the date range (e.g. if set from January 1st - March 31st, but only January and February had budgeted values, it will show that $0.00 was budgeted in the period).
