How to fix duplicated VAT @15% line on Bills.
When creating bills, QBO reflects two VAT @ 15% on R** lines - under the SUBTOTAL line. QBO includes this duplication in the calculation of the bill total. If I delete the amount in the second line, QBO reflects the correct total bill amount, but still flashes this error message "Were sorry, QuickBooks encountered an error while calculating tax. Try reselecting the tax rate or reentering the product/service item and saving the form again."
