Google Earth Engine export creates multiple tiles with gaps between them

I am working with Sentinel-2 Surface reflectance data in Google Earth Engine and exporting a mutli-band composite (spectral bands + vegetations indices) for further analysis in ArcGIS Pro.

My workflow is roughly as follows:

Cloud masking using SCL band
Filtering by date and cloud percentage
Creating a median composite
Computing multiple indices (NDVI, EVI, SAVI, NDWI, etc.)
Stacking all bands into a final composite
Exporting using Export.image.toDrive()

Here is a simplified version of my export:

Export.image.toDrive({

  image: finalComposite,

  description: 'ECA_2025_S2',

  region: roi,

  scale: 10,

  maxPixels: 1e13

});

Problem

The export produces two GeoTIFF files instead of one, even though I expected a single image.

When I load both rasters into ArcGIS Pro, I notice a very thin gap (1–2 pixels) between the two images.

This looks similar to a seamline or pixel alignment issue.

How can I ensure a single exported image with no gap or misalignment between tiles?

Any suggestions or best practices for handling this in GEE or ArcGIS Pro?
