DL3 color is off

We are rigging a TV show that will have 3 DL3's in the rig. Today I pulled them out and tested them. One of them the color is way off. Everything that should be yellow is magenta and everything that blue is green. What would make the colors switch? I had them running side by side with the same image file. It's the only wide lens the other two are regular lenses. Could they have messed something up when changing the lens before the rental house sent it out?
Thanks in advance,
