After Effects is creating a green color cast flicker on video

Hello,

I have a clip that is 120 fps that I am time ramping in After effects. However, the issue persists even without the time remapping. I am adding Lumetri to the clip in AE. 

There's a flicker of green color cast throughout the clip on the timeline and on export. The clip is attached with time remapping. If you go frame by frame, you can see the flickering. It's very subtle. 

Project settings are 2.4 Rec 709. Any other settings I should check?
