Desaturation when exporting

I'm having an issue whenever I export from premier, the exported video becomes desatuated and the black levels/contast go up on certain video clips. I tried downloading the lut from Adobe but that only made the issue worse. I have a Mac, so if anyone has any suggestions on how to fix this it would be greatly appreciated!
