Hi
You can delete one version of job by
1. Open the Navigator viewer.
2. Expand the your_project_name folder, and then process folder.
3. Delete the three files: jobName\_0.2.item, jobName_0.2.properties and jobName_0.2.screenshot.
4. Back to Repository and fresh the job list, you will see only the version 0.1 exists now.
