Hello there
I'm at the final step of the core designer certif and have 4 invalid cells in the row on countries ( cote d'ivoire, Vatican,Rdc , Timor) .
I'm not sure it is normal as I dont see any mention about that in the instructions. Can you just tell me if tit is part of the exercise? Also I dont understand why these ones only are shown as invalid.
