Finding a historic license

I can’t be the only one having this problem?

Youtube has flagged a copyright claim on a video using a licensed track from Envato Elements. I know I licensed the track but the project was 2+ years ago. How do I find the license now?

It takes forever to sift through the 50+ pages of downloads and I can’t see anywhere where to search in the downloads or look through my projects to find the license.

Please help!
