Is the traffic signal at Glen & Broadway broken?

The intersection at Glen & Broadway has crossing buttons for cyclists which don't do anything. Or at least, they don't cause the walk signals to activate, and it feels like it isn't extending the duration of the green light going across Broadway.

I suppose the walk signals are for walkers, but it seems weird that the buttons do nothing.

Should I report this intersection to the city? Or is there some reason for it being like this?
