Multibar Rests Not Happening

I’m having a devil of a time with multibar rests. This is a newly created arrangement in Dorico, not an XML import. I’ve gone painstakingly through the Help manual, what I could find in this forum and via Google search. None of the signpost, delete barlines, properties, layout, setup or other guidance does the trick. This is a first effort from a long-time Finale user. Most of the Dorico processes have been reasonably straightforward, but not this one.

Image is supposed to show that no signposts are showing. In Engraving, however, section B and all subsequent multiple bars of rest will not work.

Have you set the Layout Options>Players>Bar rests and multi-bar rests to consolidate multibar rests for this layout?

Yes, I’ve tried that any number of times on the Full Score and various parts.

Post the file (cut it down to just the clarinet).

There is a Chord Symbol Region covering from bar 1 to 39. Show it by selecting Highlight Chord Symbol Regions in the View menu. Select it and delete it.

Thank you, Steven & Janus. It took me a while to sort how to actually delete that region but once found seemed to do the trick. Appreciate you.
