In Ondemand, when the JIRA Agile license has expired or if the user has not purchased the Agile license, we do not show the Agile menu.

However, the Sprint and Epic Link fields get added to the Default screens. Users could remove the fields from the screens, however every time JIRA restarts and the JIRA Agile upgrade task is run, the field appear back on the screens.

Only workaround is to uninstall the Agile Plugin.
