copy pasting audio from After Effects to Premiere results in gain and alters the audio

Ae 2021 18.4.1 Premiere 2021 15.4.1

when copy pasting or opening a premiere project that comes from an Ae composition, the audio has a yellow fx badge indicated modified properties (I have not done anything to the audio in After Effects). even when properties are deleted (remove attributes), the yellow fx is still there, and there is still a gain in the audio. if you drag and drop the same audio from project panel in premiere to the timeline - it is unaltered. it is not clear how/why it was modified and how to remove it.

if there is an explanation for this and this is not a bug, please share with me.
here's a recording of the issue:

notice the waveform of the audio coming from after effects, and notice that even if I remove attributes, it's still yellow fx badge, and there is still a gain in the audio. there are no adjusted keyframes in the audio. why is it yellow fx even if I remove the attributes? how do I reset it (other that dragging the original from project panel to timeline)?
