I just noticed this after patch 2.1.
In the duty finder dungeon list, Toto-Rak is listed as "The Thousand Maws of TotoRak" without a hyphen. In the flavor text on the right side of the window describing the dungeon, the first mention of the name is written as "Toto--Rak" with two hyphens.
Also, Tam-Tara is the same way. The list says "TamTara Deepcroft" without the hyphen.
