So I did the save data transfer from my Wii to my Wii U. Black Ops 1, Modern Warfare and World at War all did fine. The MW3 profile transferred but all my stats were reset to zero and I'm back to lvl 1

This was my second Wii (first one quit reading discs) so I did the same thing with my original Wii. Everything worked fine except MW3. Once again profile transferred but everything reset to zero and back to lvl 1.
Anyone else has these issues? I wonder why MW3 didn't work? The only thing I can figure is that my profiles were hacked on both Wiis for MW3. Not by me but some **** hacker.
