Hello,
You can try to use trim function not in the Timeline and Storyboard areas, but in the video/effects zone. See the attachment one. After trimming, you will receive some different, separate files, to work with on Timeline or Storyboard. See the attachment two.
Please note, that after you deleted some fragments as shown on the attachment three, there is no need to merge the rest fragments, as they will be merged automatically.
Best Regards
