In the older interface when you filtered by epic it filtered on only that epic. If I clicked on another epic the first one would be de-selected, and the new epic would be shown.
This allowed for easy review and prioritization of tasks on an epic by epic basis.
With the new interface I can't find any way to do this. Epics are hidden by default, and when shown if I select one epic, then another epic, issues from both epics are shown instead of the last epic that I selected.
This makes it much harder to review tasks and users are prone to forget that they have more than one epic selected, causing them to create new issues in the wrong epic, and then they are lost in the shuffle of the hundreds of open issues.
How can I force the interface back to the old behavior?
