FCP chapter markers and poster frames issue

Hi Forum,

I create chapter markers in FCP project, name them and create poster frame for each chapter marker then export them. The export file shows chapter markers, but NOT chapter makers's name and poster frames. To fix it I've tried the same in Compressor, however, no avail.
FYI, I'd no issue with with this in using old classic QT. I wonder if it's a missing feature?.

Planning to do a batch job for this in compressor, any advice?  

I use FCP 10.6.1 Compressor 4.6

Much appreciate for the support,
Soran. 

Where/how are you looking at these files after you export them?
