When I clicked on a formula metric from a Project, I found that I couldn't sort the values in the page. So there are a lot of blank spots and a few values scattered within, so I thought if I tried to 'sort value' then the researched answers would cluster to the top or bottom.
Also the bar graph shows all the values being the same.
This is a good ticket. Easily reproduced, and it looks like you're right that it only happens when filtering is on.
To be slightly more specific, I think this is a problem with searches that involve not-researched metrics (including "All"). Filtering by the project alone doesn't break the sort (fwiw).
