As @DarkStar says, FAQs or a ticket to Official IK Support is normally the best route for issues. This is a user-to-user forum and so the responses you get will depend on whether other users are having the same problems with the same equipment.
That said, it's unlikely that you are experiencing a fault with either the iRig Pro I/O or the iRig Acoustic Stage. Both of these are mono pieces of equipment and so you will never get stereo from them. The iRig Pro I/O has a single XLR/jack combi input and the iRig Acoustic Stage is a single mic. These will report themselves to the recording software as such. It's possible that the DSP unit sends 2 channels through the USB if you have a secondary input plugged into the AUX connection, but it doesn't mention it in the user manual. I haven't used one so can't confirm how it would work.
What you can do (so you hear the audio in both sides of headphones/monitors) depends on what your recording software is and can do. If you have recorded a mono track then you could pan this centrally if your software allows and you will hear it through both left and right. Alternatively you might need to make this mono audio into a dual mono file which should also mean you get it in both sides of your headphones. It is possible that you have set the software to record a stereo file but, with only a single channel being reported to the software, it will only have recorded onto the left channel of the file. At this point it is going to come down to what your software allows and how you've recorded the audio you're having issues with.
