Looks like a tagging issue to me.
JRiver can tag WAV ID3 style but you have to enable it explicitly.
In 16, enable WAV tagging http://wiki.jriver.com/index.php/WAV_%26_AIFF_Tagging
Then use Library Tools > Update Tags from Library
Roseval, Thank you very much, you made my day, Merry Christmas!
Great tip, genius of the day!
I would have never found that searching support!
