Sorry, it looks like the IR lights on your Dolphinbar broke, which is a common problem with it. Take a close look at it with your camera. You should see 5 IR lights left and right each. On the photo i can only see 3 on the left side.
Theoretically it's possible to fix it by soldering new IR lights to it, but i don't have a clue which lights you'd need to get as replacement. After my Dolphinbar broke, i switched to a pure sensor bar(only IR source) and a bluetooth adapter in passthrough mode, because i don't know the 1st thing about soldering and i don't want to buy a new Dolphin bar only to have to break eventually as well.
