Dragons taken not showing up [GAMEPLAY]

while playing a game one of my friends said that he wasn't able to see how many dragons had been taken. After a while of him getting frustrated saying that he really cant see it he decided to share his screen and to my surprise he really couldn't. Hes running his league of legends on a mac.
