Color not sending transitions and filters back to FCP 7

Hey People!

I'm currently editing a 30 minute doc for broadcast in Final Cut Pro 7. Before sending to color, I duplicated the master and made it into two 15 minute halves.

I left all transitions and effects intact, which I usually do. I only use cross dissolves. All video is on Track 1.

After correcting the first half I sent it back to FCP without an issue. Transitions and filters remained.

When I finished up with the second half and sent it back to FCP - there were no transitions or filters.

I've tried re-conforming and re-rendering but with no luck.

Any ideas/suggestions would be greatly appreciated. Thanks.
