Hello guys,
I have some problems on pull request analysis behavior,

I have created a pull request from branch sonarqube_4 to branch develop and trigger a Jenkins pipeline to analysis.
In the first try, SonarQube detect three files change as expected and report Overview about duplication, coverage on these three files.

I added a new commit (that add a new file) on branch sonarqube_4 and push, the Jenkins pipeline run again. In this second try, SonarQube only report Overview about change in this new commit. I lost Overview about duplication and coverage on three files change before. What i expected is Overview on all the different between branch sonarqube_4 and branch develop. Is it common action of SonarQube? Can I configure to work as my expect?

In the below pictures, SonarQube only report Overview on new file lala.py added by new commit and omit three files remain:
