Calibre sending files to wrong location on Nook

Not sure when this happened but after a previous update I noticed I could not SEE the books I just sent to device. After a little investigation I see that they are not getting sent to NOOK/MyFiles/Books/ anymore. Now they are getting sent to NOOK/Books/. So Calibre sees they are on the device but you can NOT view files on nook in this folder. I have to manually move them to the correct folder in order to access them on my device. Can you fix this problem so it loads correctly again?
