I expect someone from zero88 will be along in the morning with better advice but, in the meantime, can I pick up on a couple of things that I'm pretty sure they will ask about.
If the desk isn't connected to the packs then it cannot be responsible for things that start after it is disconnected. Worse case scenario here is that the dimmer packs 'remember' the last state before the disconnection. Not sure if your packs do this, Z88 person will, no doubt, confirm.
Do you leave your dimmer packs on 24/7? This isn't a good idea in any case, they are using current even when they are at zero% on the desk an there's generally current going through anything attached to them. If nothing else this is bad for the electricity bill. If they are off they can't go silly at 3am either.
Lastly, it's a long shot, but mention roughly where you are. There's a chance there's an experienced forum member in your vicinity who would be willing to take a look at your set up. I'm Milton Keynes based myself if you are somewhere near me.
