Issue Summary

parentEpic JQL continues to list the subtask after the  parent story is unlinked from EPIC.

Steps to Reproduce

1. Have a Story having a Subtask under an Epic,
2. Run the JQL parentEpic = Epic, it lists both Story and Subtask.
3. Unlink the Story from the EPIC, the Subtask still shows up in the JQL result.

Expected Results

The subtask should no more show in the JQL result as the link between the parent story/task and Epic is not there.

Actual Results

The Subtask still shows up in the JQL result

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
