HASS Configurator: Folder View looks wrong

I’m ne to Hass and install hass.io to Ubuntu and running fine. But the add-on Configurator looks wrong if I open the folder view:

Whats wrong here and how to repair the buttons?

Regards, Steffen

I have reinstall the add on but did not work. Any help out there?

It looks like it’s not getting the icon font, which probably downloads from the internet, or you are blocking something on your browser.

Ah OK, thats possible. Do you no the url I can whitelist at my Pi-hole?

Got it: api.segment.io on whitelist an everything works.

Thank you very much!
