Cannot access hidden rooms in Ruins of Alph - Unown letters do not display?

Question

Playing Silver, not SoulSilver-

Supposedly the Unown symbols on the back of the puzzle rooms are supposed to spell hints. On mine, all the letters on the back of all the rooms are the same and they don't spell anything. I have completed all 4 puzzles. I have not completed the game.

edit: I am detecting these may not be included in Gold/Silver. If so, how then is the Moon Stone obtained?
