I don’t have the Grizzly one, but I have one made by Leecraft, which I think works really well. It doesn’t have a clip or magnet, but instead has two screws toward the front that are supposed to be backed out until you get a friction fit. This holds it in quite well. Are you sure there are no screws on yours anywhere that are supposed to provide a friction fit? It doesn’t seem right that you would have to use the leveling screws to secure it, as they are supposed to be underneath the insert and just raised or lowered by reaching through the holes with a screwdriver to adjust. If you use them to secure the insert, then you have no way to level it.
