Q-link in arrange page stopped working?

I could have sworn this use to work, but I’m trying to select multiple midi tracks and quickly solo / mute them. In the past I’m pretty sure I was able to do this by selecting all the tracks in the arrange page, and while they were highlighted use the key modifiers alt+Shift (which turns on Q-link) and if I hit the mute button all the selected midi tracks in the arrange page would mute. However, this is not actually working.

It does work in the mixer, but its not working in the arrange page.

Am I missing something? IS there some sort of toggle or preference that I might have inadvertently turned off?
