Damage Stability Analysis always fail

Hi All

Good Day 

I am doing damage stability analysis for a LPG barge. Class notation is : C Hull + Machinery.
My barge is without any double bottom, C type LPG cylinder is mounted on deck. I am just trying to check the result after a single compartment ( Largest compartment, in this case Void 3 (p)) damage)

Here attached of my tank plan and Damage case ( Damage case are defined as per IGC code)    

  

After Run with loaded departure and Void 3 (p) damaged. I got below result

Loadcase - LD With 100% Consumables

Damage Case - Void 3 P/S

Free to Trim

Specific gravity = 1.025; (Density = 1.025 tonne/m^3)

Compartments Damaged -

Compartment or Tank         Status     Perm.% PartFlood.%          PartFlood.WL

VOID 3 (P)            Fully flooded        98

Fluid analysis method: Simulate fluid movement

Now my question is why the first criteria always fail? 

Can anyone help me clarify this matter.

Thanks in advance
