Group motion icon - colour changing on state change BUT icon itself not updating

I have a number of motion sensors.

When I display motion sensors in my dashboard as single entities (in the custom:mushroom-entity-card), the icon changes as does the color. See the icons below:

Motion

No motion
image

I have grouped several motion sensors and configured it so that if one sensor detects motion, the entity reports there is motion. The icons look as follows:

Motion
image

No motion
image

The problem is, the icon when there is no-motion in the grouped sensor entity is NOT updating - i.e. it continues to show a motion icon - even though the color of the icon is updating to show no motion.

Please can someone help?

Thanks

I figured out my own problem!

Basically I had selected the motion icon in the group sensor settings (in addition to setting the sensor as a motion sensor) rather than leaving the icon in the group settings blank and allowing the system to automatically set it based on it being a motion sensor. By removing the motion sensor icon entirely from the group sensor settings fixed this.
