Memory Block usage doesn't add up??

Hello, 

 

Looking at my hierarchy, I see that one of my sub-system instances consumes 105 M9K memory blocks. However, when I count the sub-modules it only adds up to 41. Where did the other 64 blocks go? I've attached a screen shot. 

 

(the photo adds too 49 since two of the {4-block} sub-nodes are expanded)

You can get more detail on memory block usage in the Fitter section of the compilation report. It's not clear from this where the other memory blocks are being used.
