I am trying to make a LabeledSlider class that has all the logic for my slider contained within itself. Whenever I instantiate multiple of this class it causes the sliders to interact with one another when I move any of the sliders. Please help me fix this issue. My code is:

import sys
from PyQt5.QtWidgets import QMainWindow, QApplication, QSlider, QLabel, QVBoxLayout, QHBoxLayout, QWidget
from PyQt5.QtCore import Qt


class LabeledSlider(QWidget):
    def __init__(self, header="Header", orientation=Qt.Horizontal, parent=None):
        super().__init__(parent)

        # Create the slider
        self.slider = QSlider(orientation)
        self.slider.valueChanged.connect(self.update_label)

        # Create the header
        self.header = QLabel(header)
        self.header.setAlignment(Qt.AlignLeft)

        # Create the label
        self.label = QLabel('0')
        self.label.setAlignment(Qt.AlignLeft)

        # Create the layout and add widgets
        self.layout = QVBoxLayout(self)
        self.layout.addWidget(self.header)

        self.innerLayout = QHBoxLayout()
        self.layout.addLayout(self.innerLayout)

        self.innerLayout.addWidget(self.slider)
        self.innerLayout.addWidget(self.label)

        # Set the initial label value
        self.update_label(self.slider.value())

    def update_label(self, value):
        self.label.setText(str(value))


class MainWindow(QMainWindow):
    def __init__(self):
        super().__init__()
        self.setWindowTitle('Labeled Slider Example')

        # Create the layout and add labeled sliders
        layout = QHBoxLayout()
        left_layout = QVBoxLayout()
        right_layout = QVBoxLayout()
        layout.addLayout(left_layout)
        layout.addLayout(right_layout)

        # Left side
        slider = LabeledSlider("Slider 1", Qt.Horizontal)
        left_layout.addWidget(slider)
        slider = LabeledSlider("Slider 2", Qt.Horizontal)
        left_layout.addWidget(slider)
        slider = LabeledSlider("Slider 3", Qt.Horizontal)
        left_layout.addWidget(slider)

        # Right side
        slider = LabeledSlider("Slider 4", Qt.Horizontal)
        right_layout.addWidget(slider)
        slider = LabeledSlider("Slider 5", Qt.Horizontal)
        right_layout.addWidget(slider)
        slider = LabeledSlider("Slider 6", Qt.Horizontal)
        right_layout.addWidget(slider)

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


if __name__ == "__main__":
    app = QApplication(sys.argv)

    window = MainWindow()
    window.show()

    sys.exit(app.exec_())

I am not sure where the error may be to start trying things.
