There seem to be issues with putting the War-Steed items into the Store properly in quite some cases. Often, they cannot be found by browsing the Store via its menu.

Alternatively, try typing "Bone Set" into the search box in the Store window (upper right area of the window) and press the "Search" button. Usually, a direct search by keyword brings up whatever steed or steed cosmetic has not been linked properly.
