Audacity Refuses to Record in Stereo

Help!!! I’m using Audacity (the latest) to digitise masses of cassettes and reel-reel tapes and vinyl records. BUT it has a major flaw. Even though I’m using a Lenco stereo transcription deck and a dual stereo cassette and a stereo reel-reel deck - the end result is always in mono.

The stereo recordings are digitised as confirmed by monitoring the input to the digitisation device. However the output is recorded by Audacity as in mono.

The chain is this:

Lenco Transcription deck > analogue stereo output
Akai 4000Ds Mk Ii Reel To Reel > analogue stereo output
Double Cassette Player > analogue stereo output

Behringer UFO202 UPhono USB Audio Interface > analogue stereo input # digital stereo output
Griffin GC16035 iMic USB Audio Adapter > analogue stereo input # digital stereo output

USB (2.0 or 3.0) port on Dell Inspiron laptop > digital stereo input

Audacity > digital MONO output (the right channel is lost, the left channel is recorded on both right and left channels of the resultant

Has anyone here got any suggestions please.

Thank you - Chris B.
