I noticed that the icon of the "Advanced Mate menu" can no longer be changed and is now set to the icon provided by the theme as "start-here".
The change was asked here as "an option":
https://github.com/ubuntu-mate/mate-menu/issues/45
The problem I have is that I want to use "Numix circle" as my theme, but I don't want to have a red circle with an "n" in the panel (the left part of the image is my current setup and the right one is UM19.10 running in a VM).
Numix is a theme that can be applied to many distributions. They provide a generic "start-here", a version for Arch ("start-here-arch"), a version for KDE ("start-here-kde" and a symbolic version "start-here-symbolic".
If they decide to make a version for mate, it will not be used unless they called it "start-here" or I overwrite the icon.
I think this option is fine only for themes made specific for Mate.
