Do you mean a GNOME Shell extension? The gnome-system-monitor package 
doesn't contain a GNOME Shell extension, only a standalone application 
(/usr/bin/gnome-system-monitor, "System Monitor" in the apps menu).

There is a packaged GNOME Shell extension related to 
gnome-system-monitor in the gnome-shell-extension-system-monitor 
package, which is part of the gnome-shell-extensions source package.

This is not an extension that is provided by Debian. Probably you 
installed it from <https://extensions.gnome.org/> or Github? Debian is 
not responsible for third-party extensions.

This might be 
<https://github.com/mgalgs/gnome-shell-system-monitor-next-applet/issues/143>.
