Render 5.1 Regions/Tracks to New Montage - Empty

Renders don’t open as expected in New Montage when rendering a multi-mono 5.1 montage as Regions/Tracks multi-mono with Create Montage selected. The new montage created is empty.

Also if I render the 5.1 to Whole Montage with Create Montage selected and file format Multi-Mono, the new montage is either all tracks bussed to Center (if I select None button in the montage template selection), or with multiple empty tracks in the new montage (if I select a custom montage template).
