I faced a similar problem a while ago. To fixed it, I have uninstalled and reinstalled the application. Since all the data is in the cloud, nothing was lost.

Might help to try...

If you haven't done so already, would it be possible to submit an iPhone & iPod touch app issue report via our support system?

Please select the issue that you're experiencing from the list on the left, and follow the steps shown. If your issue isn't listed, just click on "I'd like to report a new issue" on the left.

Your report should provide all the info that we need to investigate further, but we'll be in touch via email if we require any more details.

Reinstalling may help, but we like to know as many details as possible to track down any bugs/crashes/etc.

Thanks!
