first, a track's mixer gain should affect the so called "clean" sound and only; thus when you set to minimum you should ear silence from that track and from that track only.
second, an aux-send gain affects the signal that is directed to the target bus; where it is mix-down with the signal from other tracks that possibly have the same bus as designated output.
not much has changed in this regard since the thread has started from years ago.
please check again your tracks-to-buses chain setup as it seems that something more is happening than what you describe.
