PROXIE AUDIO CHANNEL ERRORS: Proxy Media and Full Resolution Media must have matching audio channels

I have issues on my proxies I have exported with ingested pre-sets. I spent most on my project exporting low quality, MP4 versions of my MOV files. Then this error pops up and stating that it does not have the same amount of audio channels.
I really do not want to export my files again because I have been do this so many times and they are all exported into the pre-set my ingest just used. If I do need to export them again, what is the DEFINITIVE pre-set I can use to be sure that my proxie is usable in this project.
