ControlP5 Button Labels Made Upper Case

I am using the ControlP5 library to create buttons on the GUI. ControlP5 alters all characters I put in a button’s label to be in upper case. This is undesirable for me. Can this be prevented?

worst case try

/** ControlP5 Button * by Andreas Schlegel, 2012 * www.sojamo.de/libraries/controlp5 */
 
import controlP5.*;
ControlP5 cp5;

void setup() {
  size(300,200);
  cp5 = new ControlP5(this);
  cp5.addButton("button")
     .setValue(0)
     .setPosition(100,100)
     .setSize(100,19)
     .setLabel("") 
     ;

  cp5.addLabel("my button text as label")
     .setPosition(100,100)
     .setSize(100,19)
     ;
     
     
  // ControlP5.printPublicMethodsFor(Button.class);
}

void draw() {
  background(200,200,0);
}

public void button(int theValue) {
  println("a button event : "+theValue);
}
