What is a “memo note?” Manager does not include any such transaction form. The title of your form mentions goods received. But you mention printing an invoice. This is clearly not a goods receipt, because you have included discounts. Referring to transactions by their real names will help you get answers.
Are you complaining because the program does not show all quantities with the same number of decimal places? This is because the general design philosophy is to suppress unnecessary information. The program is not a spreadsheet in which you an force standard formats.
Or are you complaining that the quantity column does not include the unit of measure after each entry? That is because all are the same. When all are the same, the program substitutes your unit designation for the default Qty heading. If they have different units of measure, all are separately labeled in the line.
It also appears you are using a custom theme. Users are responsible for the performance of their own custom themes.
