Help on Extended comments it does not shows when I click Print extended comments

Hello, I did read some comments but this seems to be a little different,  

when I print a regular sales order without checking the extended comment box I do get the purchase order just like the figure above. Notice that the last item MMLSP200-2 shows a description which is by the way all Description for this particular item.

  But when I click Print Extended Item Description the item  MMLSP200-2  does not show the comment. see figure below the rest have the extended comment but the last one does not. and there is a description as you can see in the first picture.

I appreciate your help.   (I am using Sage 100 Adv. Version 5.30.2.0)

Thank you.
