Those grains don't need to be mashed. I have had one or two problems regarding my OG when brewing extract, for instance, if you are topping up with cold water at the end of the boil, make sure you give the wort a big stir after adding it to ensure it's even, this might be your problem and it's hard to get an accurate reading
