No Track References in the Exported Labels file

I am on Audacity 3.0.2 on Windows 10 (Updated with Latest Version)

When I use Edit Labels via the Audacity UI,

For each Label in the first column I get a reference to the Track.
However when I export it, that column is missing.

Wonder whether there is any setting somewhere to include that column (and/or additional columns to a Label).
I have searched through preferences and I am not able to see any menus for this.

I am using the Label files with my [Python] Audio Composer, where I combine audio segments in flexible and powerful ways to assemble Songs.

Thanks in advance

Sri.
