Quite frankly...because it hasn't been cofirmed. It was a single cover page, similar to the one where Elizabeth is chained in a dungeon, or Meliodas and Ban are shown riding dragons, or the cover page where a group of 6 Meliodas' grope Elizabeth. All we know is that Meliodas was affiliated with The Kingdom of Danafor. Not a single character has said he was a Holy Knight - not even Cain/Barzad. Was Liz a Holy Knight? Most likely, but until it's outright stated we won't include her either.
