mass defect with compressibleInterFoam

I have a problem using compressibleInterFoam. I set up a small test case for myself to investigate different boundary conditions, therefore the test case was very small. As I noticed, the water in my test case disappears over time. I then started investigating the tutorial case depthCharge2D, since this was the case I started out from using compressibleInterFoam. I modified the case that it does not have the over pressure bubble, but only water inside the closed volume. All the walls are solid, but still, after some time the water disappears. The setFieldDict and the controlDict (set to endtime to 20 seconds) was modified.
The modified case can be downloaded here ->
http://xi.cheleb.net/files/OpenFoam/ (497kB) It is quite peculiar how the water disappears. It tried different values for gravity and this seems to affect the velocity with which the water disappears.
Maybe somebody can help
