Can't change age in account settings

While I think never aging might be cool it doesn’t look like I can show that I had a birthday this summer and +1 how old (or young!) I am. When I increase age I and click “save” I get a “Whoops, looks like something went wrong.” error. Here’s the specific URL:

Same issue, but without an error message. I can’t change age or weight.

Doh! Worked it out. My profile name had been saved with a space on the end of the given name, the error message was off the top of the screen.
