I am using multibranch pipeline in Jenkins with Branch Source plugin at https://plugins.jenkins.io/github-branch-source/
Source type: Github
Even if I set Discover branches strategy as
Exclude branches that are also filed as PR
Github reports two checks.
continuous-integration/jenkins/branch never run!
The solution: It was an issue with Github Branch Protection settings.
It is fixed when I removed
continuous-integration/jenkins/branch from above
Require status checks to pass before merging settings.
