Volume changes with time in laminar two phase flow physic ?

Hi,
When i try to use the "laminar two phase flow, level set equation", i get a strange phenomena, when i show a movie of the simulation (with time), i can see that the volume of the inner fluid is getting smaller. if i simulate for a longer time, the inner fluid can go smaller until it disappears.
in order to see if the problam is my configurations, or the simulation I opened the design in the model library under CFD module->Multiphase Tutorials->rising_bubble_2daxi (which use the same physic), i tried to simulate this design for a longer time (10 sec) and the drop in this design got smaller and disappeared also ?
does anyone know what causes this and how can i overcome this ?
Thanks in advance,
ofir.
