Problems Recording...

[Kubra]

I recently purchased a UR22 mkII so i could record my Korg Volca Bass... It works find in Cubase and records just as well. But i wanna edit the recording with Wavlab. Now i configured the Audio Streaming Setting in Wavlab to be processed threw the UR22. Cool i got sound streaming into the headphones now. I press Record and it only records sound in the left speaker. This might be because the Volca Bass is only Mono and not Stereo? Right? Is there a way for me to get some sound out of both speakers when i record my samples? I'm not sure how to do this... I need some help please.
