UHD Copy Lost Chapters

[alfindlay]

When I use DVDFAB' 11.0.2.8's UHD Main Movie copy to copy the second half of a UHD movie and play it on my LG 4k player, tab forward restarts the movie. Bdinfo indicates correctly that there are 4 chapters but says they all start at the end of the movie
Is there a setting in DVDFAB 11.0.2.8 to retain chapters or perhaps set chapters at fixed intervals?
thanks for your help.

UHD Copy should retain all chapters unless you tell it to only copy a range of chapters. Why are you splitting the chapters? Are these chapters TV show episodes? Attach the DVDFab internal log session from one of these to a new post when you have time.

to split a uhd blu ray, I put the first 46 gigs on one disc and the rest on a second disk. I split the movie at an appropriate tab.
attached is the internal log and the bdinfo scan file
