Help ObiFluid_7.0b installation issue

[Snail921]

Hi.
I created a new project, set it for Android then import the ObiFluid_7.0b.
Burst and Mathematics had been included already so I imported Collections package.
According to this page, Jobs package was replaced (included?) in the Collections now, so I have never imported Jobs to the project.
At this moment, I have two errors.
   

• NullReferenceException: Object reference not set to an instance of an object
  Obi.ComputeFluidMesherSystem..ctor (Obi.ObiSolver solver) (at Assets/Obi/Scripts/Common/Backends/Compute/Rendering/Fluid/ComputeFluidMesherSystem.cs:105)
  Obi.ObiFluidSurfaceMesher.Obi.ObiRenderer<Obi.ObiFluidSurfaceMesher>.CreateRenderSystem (Obi.ObiSolver solver) (at Assets/Obi/Scripts/Fluid/Rendering/ObiFluidSurfaceMesher.cs:53)
  Obi.ObiRenderer`1[T].RegisterRenderer (Obi.ObiSolver solver) (at Assets/Obi/Scripts/Common/Rendering/ObiRenderer.cs:47)
  Obi.ObiActorRenderer`1[T].EnableRenderer () (at Assets/Obi/Scripts/Common/Rendering/ObiActorRenderer.cs:20)
  Obi.ObiFluidSurfaceMesher.OnEnable () (at Assets/Obi/Scripts/Fluid/Rendering/ObiFluidSurfaceMesher.cs:23)
  
• Assets\Obi\Scripts\Common\Backends\Burst\DataStructures\ConstraintBatcher\ConstraintSorter.cs(144,27): error CS1501: No overload for method 'Sort' takes 1 arguments
  

The first one appeared right after I imported the ObiFluid_7.0b and the second one appeared after I imported the Collections to the project.
How should I do from here?

Thanks!
