SOS SOS Live/Park/Bling Problems

Left Theatre 3 hours ago and designer was setting up some cues. Just called me to say some very weird things are happening. Apparently (I hope I get this right - I can't check until the morning) The PARK and BLIND lights keep coming on. Yet he claims he can see changes to lights on the stage (in Blind?) but he can't save cues. If he presses the LIVE button though he can't see lights change but he can save cues. I'm not that experienced  that I can remotely fix stuff like this so he switched off and I will go in.  its that PARK and BLIND that he keeps getting in the way. What, how the PARK button lights up is totally foreign to me. Any ideas on where to start with the in the morning would be appreciated.
