Configurator ifram appear twice!

hello,
I moved to use duckdns and dnsmasq.
Now it work well.
I added the config for panel_iframe:

panel_iframe:
nodered:
title: ‘Node-Red’
icon: ‘mdi:shuffle-variant’
url: ‘http://192.168.1.xx:1880/

configurator:
title: Configurator
icon: mdi:wrench
url: ‘http://hassio.local:8123/hassio/ingress/core_configurator

backup:
title: ‘Snapshots’
icon: mdi:cloud-upload
url: ‘http://hassio.local:1627

And now, I have two “configurator” ( the first button is not working) buttons in the frame:

Also, is that correct to use the port 8123 for the configurator ?
I don’t modify the configurator config.

Many thanks for your help !
