Colorsource Spot issue

I am currently designing in a space that converted to all Colorsource fixtures with wireless Colorsource Relays. Im having two issues with the fixtures and relays. The first issue is periodically two of the colorsource spots will flash to blue for a split second, then back to the programed color. I thought that the problem was that they were losing DMX then reconnecting, so I moved the transmitter closer to the stage to a more central position and they still flicker on occasion. The second issue is when I turn off the console these same two fixtures  cycle through colors, and the relay doesnt shut the power off. After about 10 minutes I grab a ladder and just pick up one of the relays and they both turn off. I would love some advice on this issue. The show opens in about 2 days.

thanks John
