Query: reduced active ingredients

I just received the Burned out II and was surprised to see that the active ingredient citric acid is lowered from 10% to 3%, marked on the side of the container with a printed sticker. How is that going to kill my weeds and why is it not mentioned at the product description? I used 12% acetic acid before and that worked great, but doubt that a 3% acid would work the same way. (If 3% could do the trick, they would not produce 10% solutions). I am asking for full refund- wonder if I ever see the shipping fee returned.Too bad, I do need the real product, I am sure it works well, but not a watered down version I got with less than 1/3 of the active ingredients.
