You were not able to find a few expenses because you might have archived them. Or, the admin might have archived a few approved or reimbursed reports and as a result the expenses in the reports might have been archived.
To view your archived expenses:
- Go to Expenses on the left sidebar.
- Click the dropdown next to the All Expenses filter on the top and select the Archived filter. Now, all your archived expenses will be listed for you to view.
