Screengrabbing not working on multi-screens

What steps will reproduce the problem?
1. If I turn on mood lighting all LEDs work
2. If I go back to screen grabbing only one monitor works

What is the expected output? What do you see instead?
LEDS working across both monitors (monitors are setup next to each other and in 
a extended display configuration.

What version of the product are you using? On what operating system?
Software 5.10.1 revision c879c2c firmware 7.5

Please provide any additional information below.
I have noticed if I move LED 1 to the first display it works, it seems that the 
program might be only picking up what display has number one on it.
