Did I change something?

[Nat Hill IV]

I'm pretty sure mymdnite used to show the battery voltage scale starting around 24V, or at least something way above zero.  Now with it starting at zero, there is very little visual difference between my usual overnight voltage of 25.0 and my absorb voltage of 28.7.
Did I change something, and if so, how do I change it back?
Thanks!
Definitely no big deal, just curious.
