Issue Summary

When a board uses a filter that specifies an Epic Link of an Epic that has been deleted or archived, issues are returned and displayed on the board that don't match the filter used.

Steps to Reproduce

1.) Create an Epic issue and get the issue key.
2.) Create JQL filter for the Epic issue key:

"Epic Link" = TEST-1

3.) Create a board and associate it with filter.
4.) Count the number of issues returned.
5.) Delete or archive the Epic and check count.

Expected Results

Board should return no results since the filter is no longer valid:

Actual Results

Board returns issues that are not associated with the filter:

Workaround

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