Sensor entities lost symbols

Suddenly all sensor.xyz entities have lost their respective symbols and show mdi:eye.
Likewise, no data is displayed when hovering with the mouse.
The icons and hover behavior can be restored manually by reassigning them in the entity configuration.
Is there a possibility for automatic recovery, since the previously assigned correct symbol is displayed in the entity configuration?
What can cause such amnesia and how can it be avoided?

I have exactly the same problem. I don’t know how to fix it. Especially battery sensors…
