Cant remove indicators!!! (PyQt5)

[XRGYT]

im implementing a lightweight charts into a pyqt5 gui, deleting an indicator doesnt seem to be removing it. like it would stop updating and reacting with price but it was still visually there and wouldnt be removed from the chart, ive tried stuff like this and it doesnt work

Delete each line and update the chart

for indicator_name, line in list(self.indicators.items()):
    line.delete()  # Remove the line from the chart
    logging.debug(f"Deleted indicator: {indicator_name}")

# Clear the indicators dictionary
self.indicators.clear()

# Force an update or re-render of the chart to reflect changes
self.chart.repaint()  # Trigger a repaint if available
self.chart.update()   # Call update() if repaint alone is insufficient
