Mobile_app device_class battery: icon: mdi-battery-0?

Hi, all of a sudden I noticed several of my battery_level sensors of the mobile_app integration not having icon.
Checking the state I see they are supposed to set the icon to mdi:battery-0. which doesnt exist, it should probably be battery-outline?

do we have a bug?

Same for me.
Is there a solution already for this?
