I'm having a similar issue, however mine isn't showing 1.25 qt/lb. I'm trying to duplicate a friends recipe, and he didn't give me the specific ratio he used. So I tried just entering the numbers (12.5 lbs, 18.2 qt), and it keeps changing the numbers on me. When I enter 18.2, it chages the ratio to 1.5, whereas the ratio actually should be 1.456. Click OK, and it then changes to volume to 18.75 qt (1.5 qt/lb). Then I tried to go in and set it to just use 1.25 qt/lb just to see what it would do. It shows 15.63 qt until I hit tab or OK, at which point the ratio changes to 1.3, and it shows 16.25 qt. Then I try to enter 15.625 qt, it will show 1.3 in the ratio field. When I hit tab, it changes to 15.63 qt. But when I click on OK, the volume changes to 16.25 (12.5 * 1.3), which is not correct.
