Added hue light strips to existing hues light strips and don’t work

I originally ordered 4 of the hue light strips plus. Installed 2 of them on my media wall and are working great. I then added two more around back of 75” tv and they are connected through the bridge and show up in the app.
The two strips I added cannot be dimmed or controlled through the app, they just go on and stay on.
Any thoughts??
