Describe the bug
Issue only affects cover groups, not cover. When cover group is open the icon disappears and when it is closed the icon is the one of open cover.

1. Just add at least two curtains in a group.
2. Then add a button for example, which will be linked to this group.
3. When opening and closing the curtains, the wrong icons appear.

Expected behavior
I want when the curtain group is open an icon of an open curtain to appear and when it is closed an icon of closed curtains to appear
