The Duration property not copy-pasting with audio
Premiere Pro 25.1 does not relay the duration attributes (stretch\remix) from one audio track to another.
Steps to reproduce:
1) Place an audio on the timeline

2) Change its duration via the Stretch or Remix tool, or in the duration menu of the Essential Sound tab

(also note that the +- 5 seconds is always 5 even if you change it by 10 seconds or more)
3) Copy and paste the duration property on a new audio track

The new audio track remains unchanged
