Is this something you can help with or do I need to contact EU VAT Checker? I disabled this column for the export for now, but I would be awesome if we could fix this.
And is it possible to also export the column with the invoice number? This is added by the plugin itself so the admin columns. Is it also possible to do this with Admin Columns so it could be exported?
