Only just found this.
Try putting the description on the Custom tab, not the configuration tab.
You may have to go back to the profiles that you created and look when you save the file as a lib feat part, there is a place to add a description.. THIS IS WHERE YOU WANT TO ADD THE STANDARD DESCRIPTION THAT YOU WANT ANY PROFILE TO SHOW UP WITH ALL THE TIME.
To fix any existing parts created you will have to find the properties for each solid body and add the description for each on that has been created. At least that is how is is on my 2008 files yet.
