Hi Charlie,
Thanks for the Number input fix for steps. Much appreciated! 
I have another layout issue, which has been present since CS Forms beta. It is not a functional issue, just a weird presentation one, as you will see in the screenshot.
This could be a beta hangover problem, but for this slightly more complex than usual data submission form, required separate Action Groups when I built it during late-stage beta testing. The form works fine, but as you can see from the above, most of the action group display nothing in the visual rendering in CS.
Here is the actual CS layout:
As said, not a major problem, but a cleanup may be nice, visually. This is the CS Form, which has brought most of my bug or feature finds to your attention!
Many thanks,
Christopher
