Tournament selection problem, cannot select some demigods

When selecting demigods to play in the tournament after the demon assasin update, it appears that the demon assasin and occulus have pushed Oak and Erebus out of the selection screen, and there is no scroll bar to reach them.

(What I see in the selection screen is four demigods down the side, assasin side has everyone except rook, general side has Oak, greyed out occulus, queen of thorns and Sedna.  There is no way to scroll down that I can see to reach where I presume Rook and Erebus are.)
