The "Mono" button is sort of the anti-chord button. Mono only allows one note to occupy a space. Unchecking it allows chords and overlapping notes along the time line. So when you moved one note into the space of another note, it doesn't allow the other note to be there. Unchecking Mono allows notes all over the place, so to speak.

The "Clean" button is used not to clean up the notes, but to clean up the notation. So, for example, if you recorded something live, but the notes didn't hit exactly on the beat boundaries (maybe a few ticks to the left or right of the boundary), then Clean lets you display the notes properly on the boundaries, rather than having a bunch of tied sixteenth or 32nd notes right before or after the beat boundary. It makes for a "cleaner" display.
