The new job screen is missing some translations (see screenshot).
I will work on that in the next few days.
From what I can see it is within the folder and pipeline plugins.
Several PRs have already been created:
* https://github.com/jenkinsci/workflow-multibranch-plugin/pull/95
* https://github.com/jenkinsci/pipeline-plugin/pull/449
* https://github.com/jenkinsci/cloudbees-folder-plugin/pull/145
The remaining one would be on the repo https://github.com/jenkinsci/github-branch-source-plugin
