When I try to view Advanced sections in the Initialization tab of BaramFlow, there is nothing visible even though the eye icon is on the "show" position as seen in the attached pictures. Additionally when trying to initialise the case with volume fractions in the sections to be 1 while the volume fractions everywhere else to be 0, the calculation crashes and terminates. I have tried using the adaptive timestep but that crashes too (Courant number of 0.5).

To be clear, I am trying to do a Free Surface VOF simulation of slurry moving through a system where some chambers are already partially filled with slurry and the rest is supposed to be air.

Any help in this matter would be greatly appreciated.

Additionally I am adding in the full console logs below just in case it proves to be helpful.
