Budget items should have a one to many association with a breakdown of expenses that total to the budget. Sometimes it's hard to recall what the various items for a given category are that add up to the total budget.
For example, the "Home Maintenance" category for July of 2022 may have a budget of $500.00 but in a couple of months I may forget the items that I budgeted for that added up to that amount (i.e. $150.00 Pest Service, $250 Landscaping, $100.00 something else).
