Markers not exporting in mixdown

Using Audition 23.3.0.55 on an M1 Mac running Ventura 13.3

When exporting my multitrack mixdown of an entire session, the markers are not included in the resulting file. 

I have about a dozen markers in a 38-minute podcast

I choose File:Export:Multitrack Mixdown:Entire Session

I ensure the "Include markers and other metadata" is selected

I export as either .wav or .mp3, but neither file types include the markers. MacOS QuickView does not show any chapters, Forecast does not show any chapters.

I opened a session that successfully exported the markers a few months ago and tried exporting a new file, and the markers were not included.

This feels like a bug introduced recently.
