Hi foamers

I defined a box zone in topoSetDict to restrict the sampled data in a plane. However, the sampled data is not confined to the defined box zone as illustrated in the following pictures, where fractions in the red rectangular only is the supposed part to be sampled. I have no idea how this happens... Can anyone help please? Thanks in advance!

code in topoSetDict is as follows:

FoamFile
{
    version     2.0;
    format      ascii;
    class       dictionary;
    object      topoSetDict;
}

// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

actions
(
    {
        name    zone1;
        type    cellSet;
        action  new;
        source  boxToCell;
        sourceInfo
        {
            box (-0.1125 -0.1125 -0.1125) (0.4125 0.1125 0.1125);
        }
    }
    {
        name    zone1;
        type    cellZoneSet;
        action  new;
        source  setToCellZone;
        sourceInfo
        {
            set zone1;
        }
    }
    );

and code for sampled surface is listed below

sampled_surface
    {
        type                   surfaces;
        functionObjectLibs    ("libsampling.so");
        enabled                true;
        outputControl          timeStep;
        outputInterval         5;
        surfaceFormat          raw;
        interpolationScheme    cell;
        fields
        ( 
              U
              p
         );
        surfaces
        (
              front
              {
                 type        plane;
                 basePoint   (-0.075 0 0);
                 normalVector            (1 0 0);
                 //interpolate           true;
                 //traingulate             false;
                 zone        zone1;
              }
    
         ); 
     }

Hi everyone, I find this problem only happens when sampling data at run-time. The zone woks fine when using sampleDict for post-processing. Any suggestion to improve the sampling code based in controlDict please, avoiding saving enormous data for post processing.
