How to fix - property jira.i18n.description for this transition does not contain a valid i18n key

[Aaron Andrade]

I am getting a number of warning

/opt/atlassian/data/jira/log/atlassian-jira.log:2018-11-06 10:32:14,374 http-nio-9000-exec-11 WARN user 632x269792x2 um8gea IP,IP /secure/CommentAssignIssue!default.jspa [c.a.j.w.action.issue.CommentAssignIssue] The i18n keysd.workflow.itsupport.v2.transition.respond.to.support.description in property 'jira.i18n.description' for this transition does not contain a valid i18n key.

Unable to see in the UI any property called jira.i18n.description.  There were two others jira.i18n.title and jira.i18n.submit

After exporting the workflow I was able to see clearly where that warning line was reading from (refer to the 3rd meta tag);

    <action id="781" name="Ready for Support" view="fieldscreen">
      <meta name="jira.i18n.submit">sd.workflow.itsupport.v2.transition.respond.to.support.submit</meta>

I don't see the action

c.a.j.w.action.issue.CommentAssignIssue

... am I looking in the wrong place?

Finally, how do I get that property to 'contain' a valid i18n key?
