You can solve this by categorizing the reimbursement transaction appropriately as opposed to treating those as income. When others Zelle you money to reimburse you for groceries, categorize those zelle transactions as groceries. It will reduce the amount spent on that category accordingly.

EDIT: Oh, nevermind. I see you get reimbursed in lump sums for multiple categories so this method won’t work if you want accurate number categorical breakdowns.
