Unallocated Disc Space after importing Boot Camp Partition

Hey!

After importing my Boot Camp Partition into Fusion 5, I have the problem that I can see some unallocated Disc Space in Volume Management for the Volume 0. (See Pic)

I figured out that this was the OS X Disc Space which was apparent in Boot Camp.

I already cleaned up the disc by

1. Go to Virtual Machine> Settings> Hard Disks.
2. Select Clean Up Disk.

I didn't care about that untill yesterday but now I have to extend my Virtual Hard Disc and the slider starts at 233,76 GB but the actual VM HDD has a size of about 66 GB.

OS X 10.8.4

VMWare Fusion 5.0.3

Windows 8

Is there a way to clean that up and get it fixed?

Thank you in advance!
