I´ve owned it for as long as it excits, but never used it. I always use DP pitch and Loooove it!!

BUUUUUT!!! I wanted to try out WT today and see what this plugin can do and if I somehow could make it useful in my workflow. I´m thinking of using it as a stereo pitch fixer on an AUX track for multiple mic recordings on the same instrument.
I tried to tune an upright bass (stereo mic recording) that was played in the C0 and C1 area.
WAVES TUNE did scan, but many notes did not show up at all. Only the top notes where drawn and left all the others in the dark.
Unfortunately I can´t make WAVES TUNE to see nor show the notes at C1 or below eventhough the whole area is selected.
DP pitch is showing these notes correctly and I can pitch them from there.
But in the WavesTune I can´t.
What am i doing wrong? Any suggestions?
I checked and searched the owners manual and Internet without luck.
Can anyone reproduce this problem??
Thanks
