Copied audio layer is changed when pasted - is this a bug?

I have 2 composite shots. 1 is consisted simply of a layer containing audio that was originally cut from the middle of a song.
When i copy said layer and paste it into the other composite shot, for some reason the pasted audio is a different part of the song (The part exactly after the cut i made for some reason), and it even has a different length.

How to reproduce - Put a song in the timeline, cut a part of it, right click and "make composite shot". copy the audio layer and paste it in another composite shot.

Anyone else experiencing this?
