In the material supplied there's an audio editing error at the head of the music that begins at 14.05.047. which may be contributing to the issue.
Note the a small audio clip at the head of the music, followed by a clip that contains the balance of the tune...
Expand the timeline with the slider at the bottom-right of the window, right-click in the small clip and REMOVE ALL FADES.
Do the same for the following clip.
Right-click on the split line between the two and UN-SPLIT CLIPS.
Now double-click the single audio clip and program the fades.
When inserting video splits, be sure that the audio track isn't being split as well - unless that's the intent.
Use the SPLIT button under the preview window. Click the chevron at the right side of the button and choose the specific track to be split.
