Label Refresh Function Does Not Work With ACM Package

I'm trying to setup a function that takes input from a user and prints it onto a label and updates it per entry. The updating would occur through removing the old label and then adding a label with the updated value. The text would be center-aligned. While I'm able to get the label to print the current value of "entry", it does so without removing the label with the old value.

I tried reversing the add(label) and remove(label) to see if there is a syntax error with remove, and I determined from the label not being there at all that remove was called correctly. I have kept the loop infinite for debugging purposes to work with various test cases as they come to me.

Java Code:

import acm.graphics.*;
import acm.program.*;
public class testCanvas extends ConsoleProgram {
public void run() {
GCanvas canvas = new GCanvas();
add(canvas);
String entry ="";
