Change from this in setup:

lc1.shutdown(0, false); lc1.setIntensity(0, 8); lc1.clearDisplay(0); lc2.shutdown(0, false); lc2.setIntensity(0, 8); lc2.clearDisplay(0);

To this:

lc1.shutdown(0, false); lc1.setIntensity(0, 8); lc1.clearDisplay(0);
lc2.shutdown(1, false); lc2.setIntensity(1, 8); lc2.clearDisplay(1);

Or else you just initialize and clear the first display.
