I've been exporting an ImageCollection (Sentinel-2 data) on Google Earth Engine by stacking the images with the toBands() function. Before, during image collection I've used a function to mask clouds using the Sentinel-2 QA band (maskS2clouds). Download of the stack (consisting of a single band) worked without problems but, when processing data outside GEE (some simple Grid Statistics for Polygons on SAGA) I noticed that some bands had no values at all.

Has anyone ever experienced something similar?

If so, how did he resolve the problem?
