All of a sudden, at least not due to a reason I could find, some of my sub-tasks are showing up at the bottom of our sprint board in the "Issues without epics" section. The parent task/story has an Epic Link, but these sub-tasks do not seem to have inherited the epic association.
Unfortunately Jira has rigid controls around Epic Links on sub-tasks and I am not able to show this field in order to manually fix it.
See below screenshot showing some sub-taskss in the Issues without epics section, but other sub-tasks in their appropriate Epics.
What is the cause of this and how do I resolve it?
