I think you should di a few LabVIEW tutorial first and the re-think your code. Why do you think you have to read the control via 9 seperate local variables? Remember you can branch the wire. All you need is the control terminal before the case structure and then do the rest. You can unbundle all elements with a single unbundle by name.
All you need is set the color of the element that has just changed. There is way too much duplicate code.
It would be much simpler of you would use a colorbox instead of LEDs. Now the color is the value and no property nodes are needed at all.
Another possibility would be to use picture rings. Have a look at my old code for some ideas.
