Some configuration strings are missing from the configuration page for Github Organization jobs under the Behaviors headers, leaving just the raw numerical value:

Deleting and re-adding the configuration gets it to show the English value:

but after saving and refreshing the page it will go back to the numerical value. This issue just came to my attention today, but I can't say for sure how long it's been going on, so it's hard to correlate it with a plugin upgrade, etc. We don't reconfigure those jobs very often.

I'm at a loss on how to troubleshoot, so any suggestions are welcome.
