Repeated words every 60 seconds

We just created our first podcast using Audacity. Every 60 seconds there is a small repeat loop.We can hear it at 1:09, 2:09, 4:09, 5:09, 7:09. I am guessing that there were pauses in speaking at 3:09 and 6:09. For example a speaker says “instead of” and immediately you hear “instead of” again before the conversation continues. Not sure what is the cause. The podcast is apparently too big to attach.

Are you really using Audacity 2.3.0?
