Mix Down to Mono is missing

I have what I think is one stereo track and I want to convert it to mono. I want to Mix Stereo Down to Mono in the Tracks/Mix menu rather than Spit Stereo to Mono in the Audio Track pulldown. When I go to Tracks/Mix, the option to Mix Stereo Down to Mono is not there. Not grayed out, just missing (see screenshot).


Audacity version 3.0.5, Windows 10 Pro, Version 21H1, OS build 19043.1288

Error in title, sorry. Should be Mix Stereo Down to Mono missing.

Click the little drop-down arrow to the left of the waveform and you’ll find it there.

I fixed that for you.

Where did you get that version of Audacity from?
