Rarity counter/search incorrect

Hi,

From my Home/Overview page I see a little table for "Achievements by Rarity" which as it stands show I have 1 Super Rare achievement but when I click the counter to display my Super Rare achievement it just shows me an achievement that is listed as Rare.

Similarly if I click on my Very Rare count of 70 it brings back 70 achievements that seem to vary from Very Rare all the way down to Common.

Cheers
