Export marker problem - markers are cutting or enhancing mp3 files during export

Hello,

I created an audiobook with 16 markers. Then I exported all files to separate mp3 files. 2 of the files where destroyed: they had at the end a strange loop of words or even a part of a text from a completely different chapter (marker). It seems that it appears only at the end of some files.

Because I didn't recognize, I uploaded the files to audible - GREAT!

Can somebody explain this?

Did someone have the same problem?

I am using Adobe Audition latest version 11/2024

Regards,

Mario
