(Problem) Audio fades in between cuts after export

Hi everyone,

I have a small problem when exporting a video with audio.

My project as narration and we recorded it in small bits.  I knew there could be some differences between the recordings so we took measures to reduce these differences.  When using playback in the project, the audio is perfectly fine.

However, when I export the project, there is a clear drop in audio volume at most of the audio transitions.  The drop then fades in and the volume is back to normal (the effect you see is a denoise effect, applied to each audio clip) : 

Does anyone know of any solutions to this problem?

Thanks!
