Anyone having trouble with levels 4 and 5 – Word Search : Lexagram Review

Lexagram 1.3 Been having fun playing levels 1 - 3 but levels 4 and 5 seem to be missing a significant letter. At first, I thought the letters may change each time you attempt to play. So far, every game I have played in these levels, a letter has been missing. I would hate to delete such a fun game.
