USB mixer sending left channel twice

Ok so I just got a Behringer Xenyx Q502USB interface and I tried recording it into Audacity. It records a stereo track, but it records the left channel audio in both the left and right tracks. When I plug my headphones into the mixer to monitor the input it sounds fine, I hear both channels, but when I record it via USB it’s just like having two left channels.

Is there something wrong with the mixer or is there a setting in Audacity or something that will fix this?

Couldn’t find anything online that could explain this.
