HELP! Color Changing Mid-Clip on Export

Within Premiere Pro, my clips are playing back normally and do not have any color correction, but upon export certain clips change color properties, mid clip. Across a few different videos, this occurs to different clips, at different times. Haven't found a similar post on here.

I've attached a sample and a screenshot of my export settings. These export settings haven't had this issue with any other project, and it seems odd to be occuring on different clips.  Any idea what the problem might be or how to fix this?
