When I attempt to continuously playback consecutive sections, there is a noticeable gap between them. I verified that in the Section Timing Options window I have "Wait 0 seconds..." selected. I then entered a step time midi drum beat of one measure and looped it for 8 measures. I did the same in a second section, and when they are played end-to-end, there is a pause between them.
There is no Audio yet recorded.
Copying the Sections into a new Track as Subsections eliminates the pause.
