It's not a design flaw at all, it's just not designed to be outright abused. I don't know what you hit, but with both ends fully bottomed and the tires flattened out even the BD skid plate still has ~1.5" clearance on flat ground. You probably bottomed both ends with rocks or other undulations between the wheels. The "shock block" probably prevented what would have been much more damage by buffering any further hinging of the plate about the rear mount bolt axis into the radiator/forward mounts.
While the mount points are questionable for that kind of load, you are going to find a lot of other "design flaws" if you keep putting the bike through circumstances like that and not noticing the noise or the carnage beneath you. I don't mean to sound callous, but IMO you are expecting a bit much from both the bike and the skid plate, stock or not, to be landing on whatever you did that hard(and most likely, multiple times).
Look into much stiffer springs(especially forksprings - go with ~.64kg/mm or more(stock is .59)) if you want to take an SE skyward consistently and land on flat ground, and expect not to end up in this scenario again with any skid plate installed. More bottoming resistence/progressivity in the suspension will help more than you might think, although it will still bottom somewhere and you will still need to be more consious of where/how you are landing.You will also find that the rear bumpstop is going to have a very short lifespan if you are bottoming it that hard and that consistently.
Another tip is to always flat land with an SE (or moreso, an Adventure) rear wheel first, with a little bit of power on, so that the chassis "rolls into the landing" instead of expecting both ends to just absorb all of the load. You just can't hide ~375+your weight lbs of suspended weight when it is plummeting to earth, and springs truly stiff enough to jump and flat land one would be unbearable to ride on over chatter, crossgrain and loose roly-poly rocks etc.
