Volume faders / sliders don't change the volume of some tracks.

Magix Samplitude Build 16, 64 bit. Windows 10.
The volume faders don't change the volume on some of my tracks.
I have a softsynth vst plugin (Spire) on one track and Loopcloud drums (drum machine plugin) on another and the volume won't change when I moved the faders / sliders.
I've included two screen shots.
This is the case from the mixer and also the faders in the arrangement view track.
The first screenshot shows signal on two tracks and that the faders are turned all the way down.
The second screenshot shows track 5 faders turned down but there's still signal.
I don't think I did anything different to these tracks, that would make them function differently.
Please help. Thanks.
