Hovering over the brood chamber will indicate that the total number of tiles are whatever level tile you are hovering over. Given I have a brood chamber of 5 lvl 1 tiles, 10 lvl 2 tiles, and 3 lvl 3 tiles, I should be getting 5/10/3, but instead I can get 18/0/0, 0/18/0, or 0/0/18 if I hover over a lvl 1, 2, or 3 tile within that chamber respectively.
