CableCreation and stereo

I have a CableCreation analog to USB converter. I thought it was stereo but when I plug it into the Mac’s USB port and launch Audacity, I only have the option for one mono track. Why doesn’t the other channel show up? Yes I’ve gone into setup but toggling the options there doesn’t do it.
Now, when I plug into the Mac’s analog input and select appropriately I DO get stereo. I just assumed those converters were stereo. Anyone know anything about this?

If it’s this one:
