Two Universes "Cloned" into One


Somehow I’ve managed to merge Univ 2 into Univ 1. I’m running a Road Hog 4 with a DP8000. Univ 1—4 on the Hog and 5,6 on the 8K. Had to clone Port 1 on the 8K to Port 21 to achieve Univ’s 5,6.
Not knowing if this had anything to do with it, I’ve found that Univ 2 is “cloned” into Univ 1. Both have the same DMX address w/ different Unit Numbers (i.e. 1001 and 1037 are dmx address 1. Univ 3 through 6 are not affected. If I unplug Univ 2 both still show up in Univ 1. If I unplug Univ 1 nothing shows up in Univ 2.
I didn’t notice this until I started using Effects and I’m way too far into the backups to start anew.
