Unable to disable builds for archived repository under legacy integration

I just logged into Travis and realized I still had an old repository from two years ago that was enabled under the legacy builds integration page. When I tried to disable it, I was faced with an error…

This definitely isn’t a problem with my apps being authorized in GitHub, because it shows it still has permission under the apps page.

This problem also happens when I try to enable building for another archived repository, which I didn’t want to do, but it was just to prove it is broken for archived repositories. Is there any way I can disable it? I’d rather not have that listed under my dashboard.
