Solved -

You will see other posts I made about Dragging chords [C7] in Cakewalk.

In Cakewalk after dragging from the [C7] with Chords and Block chords checked the "Create sections from Markers will NOT be enabled because the Markers are not there. The Markers must not come across when dragging. You need to Right select on the track and under Edit/Past SPECIAL make sure Markers are checked. Doesn't mater what you do with existing material. Hit "OK" and now on the time line, right select and you can now Create sections from Markers. Now the Chords appear at the top in the arranger track. I then expand the project out until all chords are visible.
