In first post you didnt say name of the character, but situation is the same as with 1st one. Info at wow-heroes is accurate. All enchants are recognized by wow-heroes but problem is that your character is using arm spec with protection enchants. 0 score is when you are using wrong enchant for that spec (mouseover option can show you that), X is the mark when you are missing enchant .
