Export Issue

Hello Forums: Export Issue

I have a question about Sonar Export - Source Search.
With 150 songs, I followed the normal selection procedure and can export from Sonar.
However, for one song, nothing appears in the Source window instead of my Audient iD14 1/2.
What's wrong here, and how can I fix it?
It doesn't matter whether I export from file or control bar.
Is there perhaps another way to export and select that I'm not aware of?

Thanks in advance for your attention.
Regards, Jack
