When you create a CSV import, one of the most important aspects is to put in the description / narrative the details of the source data, e.g. XERO TB - 200 - Sales so that you have a full audit trail between the source record and the accounts output. Currently you have a CSV import with a description column B that goes nowhere, but it just needs to be mapped to populate the Narrative in the Source Data tab. If you really want you can add a tickbox of 'take description as narrative?' but it should be an option. Seems like a very simple bit of coding too as you already bring columns A and C to your software in to the code / Dr / Cr columns.
