Audio Montage rendering to .wav will not copy/save Markers

When I render my audio montage in 8.5, which contains about 18 CD track starts,ends and splices markers, and tick the “Copy Markers” option in the Render dialogue box, the resulting .wav file has no markers whatsoever, despite having been told to retain these in the Render dialogue box…what is going wrong here ?

The markers should be visible in the audio file if you open it in the Audio File workspace. If you place the audio file in a montage without transcribing markers, the markers will not be visible until you transcribe, or right-click in the top half of the clip and select “show source rulers and markers”. Is this not happening?
