We are using Jess Frazelle's github action to clean up merged branches (https://github.com/jessfraz/branch-cleanup-action), but it leaves multiple checks:
Is that a configuration error or a bug?
It's not necessarily either one. If multple workflows that get triggered on a pull request call that Action, or a single workflow is called multiple times on the same pull request, you can see that kind of output.
I hope that helps.
