Mircostep mode change not applying

Changing the microstep mode from 16 to 8 for my extruder in configuration.h doesn't seem to take effect:

#define MICROSTEP_MODES { 16,16,16,8,8 }

It still uses the same steps/per mm and produces the same high frequency motor sound. The X, Y, Z motors still operate normal. Also, after uploading the firmware with the new value, the first time pressing the extrude 10mm slow speed button in Host will cause the printer arms to move instead of the extruder. All subsequent presses will operate the extruder.

    Oops, just learned that the Allegro A4982 stepper drivers on the Rambo support only 1/2, 1/4, and 1/16 microstepping.
