Popping noises on exported audio

Hi I am currently trying to export my vocal stems from Adobe Audition 2020 & have tried this in the earliest version that the creative cloud allows to have installed. I have changed the bit rate and tried using earlier versions to export my audio without the popping but no matter what I change, some of the stems always have popping on the stem. there's no effects or anything on the stem it's just the stem alone and it has popping noises. Any idea how to fix this?
