Epic panel shows both Done stories and "Show ... done stories" button

In Pivotal Tracker, an Epic panel typically only, by default, showed stories in the current iteration, backlog, or icebox; the only stories in the “Accepted” state that would be visible in the epic by default would be those accepted in the current iteration. But to allow the user to view stories accepted in past iterations, if there were any, a button/clickable label would be present at the top of the list of stories saying something like “Show N done stories”.

In LiteTracker currently, in an epic panel in one of my main projects, I see the label “Show 352 done stories”, and then all the accepted stories already visible below that. (And clicking the “Show …” label seems to have no effect.)
