Entire sections automatically mute themselves after I start bouncing the track.

Recording spoken audio for a podcast, and I muted the track so that I wouldn’t hear my own voice monitored in my headphones. We recorded three segments, but when I go to bounce them, the second and third segments mute the entire track. Doesn’t matter if I try bouncing the whole track or each part individually, part one comes out fine, and parts two and three mutes themselves. Not sure what I did, but please any help would be appreciated
