Just checked my collection and it seems that I have both.
1 set of yours
2 sets of the other ( I put DE3 on top of the other by accident) and 3 extra disks (1-DXA and 2xDXB)
Maybe there was 2 kind of packs over the time and they were not necessarily region specific but I'm only guessing here.
//I'm in the hunt for the original boxed pack though.
