Sounds like they messed up the chart a bit.
NAUI does not have any presence here on scubaboard so you won't get an "official" reply from them.
im a bit puzzled as to the problem, you still have the card and it's still perfectly useful for showing folks if asked for a certification, what difference does it make that they later changed the designator? If the card has worn out and you need a replacement just put in a replacement request, if they don't have have the card printer set up for scuba diver anymore then you'll probably get an open water card, still perfectly useful for getting air fills, etc.
if the issue is the error on the website, just let them know. They're not terribly quick about that kind of problem but it will absolutely get fixed within the next ten years or so.
