Cubase 11 vca fader to selected channels not working?

I don’t get it. I’m trying to add a VCA to 4 audio tracks by selecting them in the mixer and then choosing “vca fader to selected channels” and nothing happens. I’ve tried in both the mixer and the arrangement. I’ve rebooted too just in case. I can add a VCA alone but I can’t figure out how to associate it will any tracks. I’ve looked in the manual and it’s explaining how to do exactly what I’ve done. Help!

edit: I’ve just found out that if some of the tracks are linked then it does not work. Please delete this thread.
