Why am I getting double mono? (SOLVED)

I am digitising some LPs, using a Goldring Lenco GL75 deck, played through a Behringer UFO202 to a Samsung N150 netbook using Audacity 2.0.3 set to Stereo, 44,100Hz 16-bit PCM. Monitoring the recording through headphones as it happens, I get a very distinct stereo spread between tracks. Listening back to the recorded version through Audacity, I get two exactly equal tracks with no distinction between left and right. What am I doing wrong?

I managed to answer my own question by some rather more diligent searching of the forum (apologies). I needed to go into properties for the USB recording device and switch it to stereo.
