Delam is separation of glued layers normally due to moisture and subsequent woodrot. The glass will bubble under decay pressure, then it flaps with no wood and glue to hold it. In your case just wondering if the moisture came from not the inside or outside, but rather the edge of the panel. With the bumper, the flag post and the rear panel all attached to the same frame points thinking the stress of a moving flag, may be enough inertia to twist the end panel and form cracks at screw holes, allowing moisture in. That damage is centered at the pole and two years is plenty of time. Just a theory! Similar happened to me, wasn't pretty.
