Is SS72-221 decal wrong???

Well, i’m going to build an A-7E from VA-27 for my “Airwing Enterprise”…
I’ve managed to get a Super/Microscale 72-221 sheet, but when looking at all the VA-27 markings, i’ve noticed a strange thing…
It’s the CAG bird (#400), but for the wings there’s a decal for it as 406NK!!!
For the other aircrafts the decals are right, but for VA-27, no!!!
Is the aircraft marked REALLY this way, or is the decal sheet wrong (wich is my best bet!!!)???

Here’s a pic of the decal sheet…
Notice the wing decals at the bottom sides…
