These are my settings, but when I put a quantity of 10 pieces in a product that you sell for 10 euros when I go to close my fund it adds to the analysis 100.01 or 200.02 if I have a quantity of 20 pieces and a total of 100 normally, but the problem is that if I close fund the order appears with debt

• if sell 1 product with 10 euro work fine, if sell 10 or 20 or 30… has problem if close tax product from settings work but does not defer. i.e i want add product with final price with tax 10 euro if I sell the product will do the following analysis. 10 euro + tax 24% = 12,40 euro, i want sell 10 euro
