Selection wheel glitches after Demo is interrupted

Load Convertbot, go to Settings, then Support then View Demo. Now let the demo run for about 12 seconds until it gets to the unit selection. Stop the demo and return to the category selection and you'll notice some of the categories are missing. In other cases, the category 'slices' are out of position.

Confirmed on an iPhone 3GS and iPod Touch 2nd gen. Both apps were removed and re-installed but bug still appears.
