It may be a matter of programming that needs to be installed, updated, or fixed. If it can convert and display properly in the Finds and Hides tabs, then, logically it should convert and display under the BadgeGen tab. Can you refer this to those who were updating the programming when the badges were being updated?
LOL, yes, I realize that imperial vs. metric is a joke with you folks across the pond and I wish the US had converted years ago but I don't make policy in America.
