Map Skills to Display bug

Hey, guys...I've been getting a bug where the skills I map to the second and third rows (from the right of my screen) are just...disappearing. The first (farthest to the right) set is just fine...the rest are gone.
They still show in the Mapping function...but they aren't there in the Main display (and they aren't invisible, either...there is no function except movement when you touch those spots on the screen.) Re-mapping doesn't seem to help, either...only a re-load works...and then; only for a level or so.
I'm running a Samsung Moment.

Tap the spellbook in the upper right of the hud to toggle between one column visible and all columns visible.

Ohh...*DUH*.
Thanks!
