Clips without orange at top do not show titles, panning, etc.

I started having trouble getting titles to show on certain portions of my projects.  The only difference I could notice was that the titles could only show on sections where there was a thin orange line at the top, which starts and stops at various clips.  Previous projects have had the orange line all the way through and showed titles just fine.  After not finding any answers online, I decided to just be thankful that I could make do with titles in the sections with the orange.  However, I then spent a lot of time Panning and Zooming on a clip and then not see any changes when I closed the Pan & Zoom window.  Again, that clip was missing the orange header line. 

It looks possible for me to move some clips to different sections with the orange and have it work, but Deleting and Closing Gaps tends to shift it all back.  I have already invested a lot of time in this project and would appreciate any advice to help me avoid having to start over.  Thank you.
