I am using Jira Server, I assume the behavior is the same as Data Center.
I have two projects, PT and PPM, both have epics and stories. Both are of type Software.
When I view an epic in PT, I see the stories in a table with several columns:
Key, Summary, Assignee, Status, and a few custom fields.
When I view an epic in PPM, the table has just 6 columns:
A checkbox (resolved or not), Key, Summary, Issue Type, Status, Assignee
I have reviewed the installed add-ons and I don't see an add-on that can be responsible for that.
In both epics there is no Settings icon next to the list.
Any idea?
