I just bougth the game and the Untold Legends DLC while it was on the flashsale. But sofar the olny thing I see on my games shelf for my account is the base game and no sight of the DLC. And we I go to the shoppage for the DLC it also does not show me that I own it already. Is this a bug or is there no extra installer for the DLC?

Problem solved. Seems it was a known bug within the site design and after clicking on the refresh link it now shows the DLC. Thread can be closed.
