Selador Vivid R Cyc Lights holding green

Some of my Cyc lights are holding green when fading to black. It only happens sometimes and only when going to black.

When this happens and I take down the grand master it doesn't make a difference, the lights stay up and green. Its typically and end fixtures but sometimes happens Centre SL. 

I have unplugged the fixtures, cleaned out the filters and re-addressed them in a different order as well as unpatched and re-patched from the board and neither solution is helping.

Any ideas?
