To be sure, when you say there’s two ATVs in your home App, there’s two in the Same Room it’s assigned to? In the Rooms tab on home app? This would be wrong if you only have one ATV. 

If you set it to be a favourite, it would also be in the home tab and room tab. In this case it’s in your home app twice. The favourites (Home Tab) are just for easy access when you launch home app. 

Two in the same tab is wrong.
