Don't ask me how this happens LOL, but if you have problems with the Class/CB panel cracking around the hold down screws this may help you. Since all of mine were cracked and broken, I removed all the screws (6) and replaced them with m4-0.7x25 metric screws. I also went to hardware store (home hardware in Canada) and picked up 6 beveled washers in size 00 in the facet section. Simply thread the screw through the washer and then through the panel. It's not as neat as the original recessed screws with caps, but it does hold the panel down and doesn't look all that bad. Hope this helps someone in the same situation. See attached photos.
