XML exporting without colour grade

Hi. I have been working on a music video with some friends and have been trying out the workflow from Premiere to Davinci and back to Premiere. I received the initial edited footage, graded it, and exported it back, but the XML I sent had none of my corrections applied. I've tried multiple options and settings, even testing the XML on my own timeline in case my friend's Premiere timeline is broken, but the clips still come back completely ungraded.

I've watched numerous tutorials on this workflow and followed them exactly, but no luck. Is this an issue on my part or my friend who's editing? Are there any settings him and I both need to have on our own projects?

Any help is appreciated!
