Big unwieldy boxes often don't get treated well. Course, some of that is a function of how well they're packaged in the first place, but it could have been anything from an overzealous tightening of the straps to hold it on a palet, to being dropped, or stacked higher than specified. Too bad. Hopefully, someone with more useful info can chime in with better info. Once up and on the wall, properly supported, though, most of them should be okay.
