Jenkins Integration With Jira

I am trying to integrate Jenkins execution results with Jira Zephyr with the help of this article - https://support.smartbear.com/zephyr-squad-server/docs/en/continuous-integration/zephyr-squad-test-management-plugin-for-jenkins.html. I am able to validate the credentials. But facing issue with the Post Build Actions - Publish test result to Zephyr for JIRA . In the Jira URL able to view and select the Jira details, further to that in project name  and rest fields do not populate as mentioned in the Article. How do i proceed from here. Unable to figure out what is the root cause. Can any one help here.
