Ultra key changing color balance

This has been an unanswered question for a few months now. I'm sorry to re-post the issue but I'm really hoping someone will have some useful suggestions for me as this is killing me on a time-sensitive job.

Ultra key is changing the color balance on my footage. Here is one example. The same footage with Ultra Key turned off (left half) and turned on (right half). Any ideas what's going on here and what, if anything, I can do to avoid it?

Here's someone else with the same problem from months ago:

    Found solution, don't know about you guys, but what is fixed this for me is:

    Effects panel > Ultra key > Spill Suppression > Range

    Range value is 50 by default, I'm just put it on 0 and boom no more color problems

    I guess your green screen lighting was not proper.
    So the solution is: 
    1) Add Ultra Key to the video.
    2) Change the setting to Aggressive
    (Your video color tone might change now)
    3) Go to Matte Generation
    4) Go to Tolerance and reduce the Value. 
    (This will get back your original video color.)

    HAVE FUN

      Does your system have the sequence setting set to "Composite in linear color" on? If so, turn it off, and see what happens.

      What GPU and GPU settings do you have?

      Neil,

      Thanks for your response.

      Yes, the sequences are set to "Composite in Linear Color." Turning this on and off has no visible effect on the way UltraKey is changing color balance.

      GPU Preferences are set to "Mercury Playback Engine (CUDA)." I am running an NVIDIA Quadro K2000.

      I wish I had something more ... what other effects are in use?
