Successfully burned Blu-Ray DVD doesn't play past disc template

I have made six attempts to create a Blu-Ray DVD of a particular project, but I'm getting the same result.

The Blu-Ray burns successfully Final Cut Pro X shows but when I put it into a Blu-Ray player it doesn't play past the disc template. The disc template plays, but when I hit play it doesn't skip to the content. It loops back to the disc template.

It is only happening on this one project; all other burned projects play. Also, I burned this project onto a regular DVD and it played just fine.

I removed logo and title graphics; changed the disc template; deleted chapter markers; anything that other successful projects might not have. I can't recall what I've done differently with this project that's caused this issue.

I appreciate your help!

(Blu-Ray player is a Pioneer BD-RW BDR-SX05)
