Unfortunately the 2i2 will be like that; it does not come with a mixer applet to let you pan the 2 channels as desired. One channel is left and one is right.
Every other Focusrite unit (and most other brands) have the mixer applet with panning control, but not the 2i2.
I learned this the hard way, like you.
This is why I use my Delta much more than my Focusrite. Wish I'd have gotten the next model up.

Eventually I'll get something like an 18i20, but haven't needed to yet.
