First of all, holy shit, I missed this box set. Apparently, that's a good thing while they fix the printing error.
I had trouble telling from your picture what was wrong, so I went to the Mondo website and it's pretty obvious. The two "diamond" panels are supposed to be on opposite sides. It also appears that the plate with the runes was put on incorrectly (I wonder if they noticed that one). The "sword" rune pointing down is supposed to be along the top.
