Badge Icons for Lights Missing

Hi,
I have a minor but anoying problem by my location cards (automatically shown under locations) are missing the light bulb icon.

This result in nothing being shown when just one light is one and otherwise just a number being shown for > 2 lights being active:

Bildschirmfoto 2021-02-28 um 17.42.32
Bildschirmfoto 2021-02-28 um 17.42.55

Strangely all other icons seems to be in place (i.e. temperature or humidity):

All the lights seems to be correctly assigned model-wise. Everything is present and correct after invoking the location card itself.

I’m suddenly getting this as well. I know it worker on Tuesday, but somehow broke yesterday.
Web console output for the relevant part is:

What’s even stranger is that I se the same icon in a list and there it is shown.

Fixed it using this. All good again.

Thank you very much for this hint Mikael - this workaround worked like charm!
