BUG: VCAs cannot be muted with a Eucon controller

It is not possible to mute a VCA track using the mute button on a Eucon control surface. It works fine using the mouse or keyboard shortcut

This issue has existed for 2 years now! PLEASE can we have a fix:

THREE YEARS now and this is still not fixed!

STILL not fixed in 10.5
Very disappointing! Eucon development is seemingly abandoned by Steinberg.
