What's Wrong?

Updating a CCR to trigger on a GitHub issue-labeled trigger, with a label filter - fails with the error "Routine saved, but the GitHub trigger couldn’t be updated. Edit again to retry." It might be related to the label being new, and might be related to refreshing the CC web page. Can't repro reliably. (But I think you shouldn't prevent creating a filter on a non-existant label. That's my concern).

What Should Happen?

CCR should be updated accordingly.
