I am trying to get the "Make Up Your Mind" badge, so today I swam 1000 meters, but I broke it up into 4 swims so that I could change two to yards and two to meters; however, when I change a swim to meters, it defaults back to yards. I can only change the pool length and number of lengths but not the actual distance - and it only measure in yards. My friend has the same watch and was able to change it no problem, but mine keeps defaulting to yards. Please help!
