Exports are adding contrast

Recently Premiere Pro started adding contrast or dropping blacks on my exports. This wasnt happening until recently and i havent changed anything. Its not happening on the timeline or even in the export window if i preview and scrub back and forth, its not showing it there either, but when I export it is in the final product. What's weird about it, is when it gets to a part where ive added a second video track, like a video inside the full 16x9 video, it disappears and the gamma returns to normal for that clip. As soon as the second video track ends, its right back to crushed blacks. Almost like i have an adjustment layer on it for exports only. Please help
