Battery symbol is missing

Why has the left icon in CAST no battery symbol? All motion sensors are the same and connected to the same ZB-Bridge (1. Generation without P, FW: v1.7.0). All Batteries are new and in the Android APP they are shown as full.

Hi, kalle.
May I ask where does these device from?
Are they a proper zigbee device? or a zigbee device synced from smart-home add-on?

It’s an original Sonoff SNZB-03 from the first generation. Cast now displays the battery symbol.

So the battery symbol disappeared and now it appears again?

Yes, and I didn’t change anything.
