Labels are inconsistent with case

Labels have a weird issue with case -- they appear as all lowercase in the 'labels' settings screen, but they can appear as both UPPERCASE and lowercase in the label menu and stories.

ie:

my stories can be assigned from the dropdown: RC1 rc1 Rc1
the labels screen shows all as : rc1

I'd love to be able to consolidate all the RC1 and Rc1 items into rc1 and just drop those case instances from the menu.
