you have to differentiate size and capacity. In Espionage you can increase the capacity, the size will be adjusted automatically by the OS.
The get info shows in finder cannot show the capacity just the size, the info in Espionage shows both capacity and actual size on the disk.
Which one did you look at?
The size will be a bit bigger then the amount of data stored in the disk image, the capacity can be much larger.
So if you indeed stored 110 GB of data into it, then the size on the disk should be a bit more then that.
If it is not, then yes, something could be wrong.
I would copy the data out into a regular folder and then verify the size of the folder you copied into and compare.
Let me know how it went.
