I have a similar problem trying to change my training zones for cycling. It looks like the new updates to the site have broke the submit button. It's non-active and does nothing when you push it. Is there another forum or category to submit this type of web site bug to?
Also, Power Zones for cycling doesn't work. If you click the Show Power Zones button it...doesn't show the power zones so you can't change your FTP or zones.
I am running into the same issue. It is throwing a JavaScript error when loading the pages. This will cause the JavaScript events to not wire up. I guess it is time to manually change them on the unit itself.
