Upon configuring an item on a sales order line, note is generated redundantly by the product configurator when selecting "Calculate price" and "Calculate delivery date", as well as when clicking on the "OK" button. This could result in incorrect documentation (sales order confirmation/delivery note/invoice/sales quotation) due to duplicated/multiplicated note. Suggestion would be to mitigate above scenarios by checking through an if statement whether or not the string already exists and skip its addition in such a case.
