The recipe "English Style BItter" says that the beer should have OG/FG of 1.031SG / 1.006 SG. When the beer is brewed it says that the requirement for an English Style Bitter is in the range of FG is 1.007-1.011.
The same goes with the IBU. The recipe says the beer should have an IBU of 35.8 and the requirements when the beer is brewed says that it should be in the range of 25 IBUs to 35 IBUs.
This just results in a beer that scores very low on the Beer Matching score. I get that you don't always get the recipe all correct, but the requirements shouldn't differ.
