I saved my budget last month but I noticed a mistake that I would like to change.
You can make editions to the last 2 budgets only. Go to your dashboard and click on the previous budget and it will pop-up. Make your edits and save the budget. If there is a value that needs editing in an older budget it may also be possible to adjust your latest budget by adding or subtracting the wrong amount in the latest budget to offset the amount.
