Just did my setup for tomorrows race. Five stops softs @ Spain, with my setup all dialed in, clicked save (and the button went from green to grey as it should) and logged out.
Logged back in two minutes later, only to find that it had reset itself to default once again.

Now it's not really a problem because my practice runs tell me what my setup was, so I can dial it back in easy enough, but it's still a pain having to do this.
