Open a source file with some strings.
Normally the strings are RGB(0,80,80).
Place focus on "Profile".
Use the up and down arrows to cycle thru the schemes.
Go up to "Chalkboard".
The strings are green on nearly black.
Down to Cripsy, now they are pink on white.
Down to Default, the strings stay pink.
Wintergreen to Default or Crispy has the same issue, but more drastic things like Chalkboard do not.
So, why do some colors update as you cycle thru these, but others do not?
Clicking "Apply" seems to fix it.
