Weather-forecast not showing icons

Hey guys!

Since a few updates of HA the weather-forecast isn’t showing icons anymore. While editing the card, the icons are shown correctly in the preview.

I do not use any custom icons. HA core Install via PROXMOX scripts (tteckster).

Thank you in advance!

Your code produced icons.

This is not a case of the weather forecast as a sensor being removed a few versions back, since it was called for deprecation about 6 months ago?
It is now a service call.
