Default sampleDict with adaptive mesh refinement

Hello.

I am working with a 2D adaptive mesh refinement case. The simulation was run parallelly and upon completion I used reconstructParMesh to get the polyMesh file followed by reconstruct to get all the fields.

However, I am facing issues while post-processing.

Code:
sampleDict
{
	type 		sets;
	libs		("libsampling.so");
	
	setFormat	csv;
	fields		(alpha.water rhoE grad(Ue) mag(grad(Ue)) U);
	
	interpolationScheme	cellPoint;
	
	sets
	(	

    line_p0.01mm //0.01  ---------------------------------5
    {
        type        uniform;
        axis        y;


        start       (0.01e-3  0.0      0.0);
        end         (0.01e-3  0.15e-3   0.0);
        nPoints     500;
    }
       
    	);
    
}
However, due to refinement, the alpha size which I set to refine in dynamicMeshDict file, is not the same at different time steps. The error I am getting:

Error
Code:
Reading fields:
    volScalarField: alpha.water mag(grad(Ue))--> FOAM Warning : 
--> FOAM FATAL IO ERROR: 
size 68141 is not equal to the given value of 98360

file: /home/m/OpenFOAM/m-v1812/research/DyM/CSF/LMI_DyM2a/0.002/mag(grad(Ue))

    From function Foam::Field<Type>::Field(const Foam::word&, const Foam::dictionary&, Foam::label) [with Type = double; Foam::label = int]
    in file /home/m/OpenFOAM/OpenFOAM-v1812/src/OpenFOAM/lnInclude/Field.C at line 219.

End
How can I sample???
