Help!

Awhile back when playing this game, I got to level 30, & it then it showed that I could start games at level 30. Great! However, sometime later when I opened it up to play, level 30 option was gone! ??? What happened & how can I get it back? Ive played thru level 31 twice, & theres no level 30 starting point option. :-(
