Github Branch protection and two builds per commit

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
continuous-integration/jenkins/pr-merge

and 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.
