Opening lead K of diamonds.  Results 3NT down 3.

2♥ was alerted and explained as spades and tolerence for diamonds.  After the hand was over South explained it was hearts and a tolerance for diamonds.  South also explained that they had recently switched back to hearts and tolerance for diamonds and North had explained the way they used to play the bid.  Director was called and West explained had he been given the right information he would have bid 3♠

I was not present at the game or the discussion the director and some of other players had as to what the adjustment if any should be made.  I have been told both pairs should be considered "A" pairs and they are both among the best pairs in a large club.

If you had been the director how would you rule and why?
