When uploading a CSV / PDF, the dropdown shows "Amount" as a required field, BUT - you can also use the inflow (amount) and outflow (amount) instead.
Users shared how they were confused at first, because they didn't have a single Amount field and needed to use inflow/outflow, but that meant not using a required field.
Perhaps we can add a note in the blue information box at the top? Eg. "If you have your debits and credits in separate columns, you can use the "inflow (amount)" and "outflow (amount)" attributes instead of the Amount"
