Can't record in stereo, playback volume

Stereo/mono, playback

Not new to N-track but new to my USB interface. I can record but it will only record in the left channel. I thought I set it up right but something’s probably wrong. Also, the recording is coming out at such a low volume even though I have the levels way up. I guess that could be because it’s not in stereo… but if anyone could help me out it would be much appreciated.
