Sounds like a Bug: Compressor Audio Effect on Video Export

Hi - I think I've found a bug in Premiere Rush. I record many live music performances and regularly edit and export them in Rush. The audio in my final videos has been off for a while, and I've just realized today that it's Rush that is changing the audio settings upon export. For some reason, it sounds like Rush is adding a compressor (audio effect) to my video's audio. After realizing this and experimenting today, I can say that my music consistently sounds quite different in the videos exported from Adobe Premiere Rush vs what it sounds like when playing the video within Rush itself. Playing it within Rush, things sound exactly how they were recorded. Playing an export sounds like the audio has gone through a compressor with a high ratio and a low threshold.

Is this the intended behaviour? If so, why? It is super bizarre that Rush would add an audio effect that is quite noticable to anybody who is a music producer on the export without any way to control this. How can I disable this behaviour?
