MAIN PLAYBACK RECORDING ISSUE

Hi all, New to WL 10.
I have clips in my Audio Montage that I want to record to a single stereo track so, I open the “RECORDING” box. I have it set as a “NAMED FILE” and I’ve clicked the AUTO NUMBER box.
I have the INPUT set to MAIN PLAYBACK BUS.
When I record, i can only get a mono input? If I switch from NAMED FILE to TEMPORARY FILE it records in stereo?

I would like to record this as a NAMED FILE in stereo? Is this a bug? I remember doing this in WL 6.
Thank you for any help!

Of course this is possible, but you have to define the format here:
