AHB kits are pretty easy (but very good) and I have to think that you just measured a bad area of your wort. I bet you are in reality real close to your OG - UNLESS - they have the recipe wrong (it's happened).
Grinders Island Brewery - Pipeline
Bottled! Award winning East India Porter, Oatmeal Stout, Milk Stout, Saison fermenting at a nice controlled 85 degrees (up from 70) as it should be - weird isn't it.
