the problem is this:
screen.setRect(rectangle);

which means that on the screen it is searched only in the given rectangle.

after the loop, you have to reset the screen object:
screen = new Screen()

to restore to the whole screen.

generally it is not recommended to use screen.setRect(), since this may lead to such quirks if not reset and may be hard to debug.

--- better:
for(int i = 0; i < 4; i++) {
    Thread.sleep(3000);
    //Rectangle rectangle = new Rectangle(500, 550+(i*25), 75, 20);
    Region reg = new Region(500, 550+(i*25), 75, 20);
    //screen.setRect(rectangle);
    //String xx= screen.text();
    String xx= reg.text();
    xx= xx.substring(1);
    System.out.println("$"+xx);
   }
