Music in exported mp4 does not match music in .prel file

Hi,

I'm getting so frustrated. Been working on this issue 3 days now trying different things. Have anyone had the same problem and been able to solve it?

I have added music to a video in adobe premiere 2023 and adobe has mixed the music to fit the video clip. I added the music in the "music" session and have shortened the music by dragging the end of the music clip by the two small red arrows to the right to fit the video's end. In adobe's preview everything seems to match and seems fine. However, when I export the file to mp4 and view it in QuickTime, the music isn't matched anymore. More specific, when the video is getting to it's end, the music isn't matched and instead of having the nice music ending that I have in the preview in Adobe, I get the music suddlenly just abruptly cut as the video ends. It's like the mix that Adobe has done hasn't been added to the export, so the original music is just cut off when the video ends.

Does anyone have any idea of what I can do?

Here are my export settings:

H264, 2160x2160p, 25fps, 60Mbps

Audio setting: codec AAC, sample rate 48000 Hz, stereo, bitrate 160kbps
