Only half of my audio

Did you remember to create the second track in JK for your bass? You should have 2 mono input tracks in JK.

Thanks for your reply.
I went back to the setup and configure tracks window in JK. There are 2 input tracks as you say, the first one has my AI listed with the word LEFT. Clicking on the 2nd one brings up a dropdown box that allows you to enter the LEFT side of the AI again, or the RIGHT side, or leave it blank and that's all. I have tried entering both left and right, as well as leaving the 2nd one blank, as it explains that if you leave that box blank, the app will automatically create a stereo track. Same results in every configuration.
As far as I can see, these are my only options regarding the input tracks. The " bass guitar " is selected under instrument.
I do know that my old AI worked perfectly this way. 
Again, thanks for your input.
