Can't type decimal point in training log

Hi!
I took a break from triathlon and BT during most of my pregnancy, and just started trying to log workouts again today. I typically enter everything by hand into the mobile site from my phone - I don't have a fancy watch. For some reason, when I click on "distance," it defaults to a phone number keypad (no decimal) and not a full qwerty, so I can only enter whole numbers. I'm using an iphone5. I didn't have this issue last summer, and I like tracking workouts here. Can anyone help? Is it a bug, or a setting I can change? Thanks!
