I always try to use the National Homebrew Contest recipes to guide me in developing my next beer. But I cannot get the filters to work. If I check "winners only" and set the beer style to India Pale Ale, I expect to see appropriate results. But it never works. I get non-winners, non-IPAs, etc. I try using the "go" button, but it just deletes one or more of my filters. Can someone tell me what I am doing wrong?
