Oh jeez. Sorry about that.

@lhecker assigned himself, but I'll explain:

These translations unfortunately can't be changed in our repository; they will be overwritten by our translation service when it gets around to it. That means we need to go submit a bug (which Leonard will do!) with your findings up to them and then wait for it to propagate back to the repo.

Thanks for finding it. L will follow up with a GCS bug link which we'll use to track it internally. :)
