The stage doesn't unlock by levels but by stars. Press L1 or R1 to the locked stages to see how many stars you need to unlock the stage.
Actually, U can unlock full stages before playing stage 10 if you haven't miss too many stars.
If U want to make a save set, U must leave at least 1 star before unlock a new stage for those stage trophies.
