[Python] I want to display three identical QLabel widgets in a QGridLayout

I want to add the same Widget (a QLabel) to a layout (QGridLayout) multiple times. I only get the widget shown once.

This is my code, I would expect to see the label 3 times, I only see it once

import sys
from PyQt6.QtWidgets import QApplication, QMainWindow, QGridLayout, QWidget, QLabel

class MainWindow(QMainWindow):
def __init__(self):
super().__init__()

self.setWindowTitle("My App")

layout = QGridLayout()

label = QLabel("Test")
label1 = QLabel("Test1")
label2 = QLabel("Test2")

layout.addWidget(label, 0, 0)
layout.addWidget(label, 0, 1)
layout.addWidget(label, 0, 2)

widget = QWidget()
widget.setLayout(layout)
self.setCentralWidget(widget)


app = QApplication(sys.argv)
window = MainWindow()
window.show()

app.exec()


If I bring label1 and label2 into play as in

layout.addWidget(label, 0, 0)
layout.addWidget(label1, 0, 1)
layout.addWidget(label2, 0, 2)


then I see all 3 (different) labels as I would expect.

So is only being able to use a widget in a layout once by design? If yes then why? Or am I missing something?
