Did you install the GRLs while logged in as root? If you did not, then first remove all the installed GRLs, one-by-one, by using the granular -r command as the root user. Then log in as root using the GUI method (if you didn't do this in the previous step) and install them one at a time. Say, you install ActionCube first. After its installation, wait for a few seconds for its entry to appear in Menu > Other. It it does not appear automatically, then log out and log back in to find it in its appropriate place (Menu > Other). Similarly install the others.
For now, you can check if all these GRLs have been installed by using these commands, respectively, for the packages installed:
actioncube
assaultcube
lightzone
Remember to be logged in as the root user to install these packages.
