Certain fixtures randomly changing colors after update


I recently updated my etc element from version 2.1 to the newest version 2.6 I believe ( I just got it off the website). After the update some of my fixtures have been doing weird things. I have 4 seachangers attached to source 4s that will randomly change colors thought a show. I am also unable to fully control a set of vivid fire and ice fixtures. They can only do one color. I have not changed anything on the board and I added a DMX Terminator just to be sure but that didn't help. Everything else in the DMX line works except these fixtures. Any ideas as why this could be happening? Thanks for any assistance.

Also I do not want to down grade my version to an older one. That is a last resort
