My Utilities category is missing from my budget dashboard, it was there at one point. It is not set to hide.
A couple thoughts, are you certain that it’s on the Categories sheet? Perhaps an accidental edit cleared that cell. If it’s definitely there on the Categories sheet, how many categories do you have? Some budget dashboards have hidden rows you can unhide to expand and see more of your categories. By default you can see 100 categories on one of the dashboards so it really just depends on what your dashboard looks like. Feel free to share a screenshot here.
