Less Classes than specified when Exporting Index Values and Rates as Polygon

Hi,
I would like to classify NDVI index map into 10 classes using method Equal Spacing and than export resoults to Polygon Shapefile. Unfortunately after the export I get only 8 classes and empty spaces without any polygon in extremely values. It seems that I always receive two classes less than expected. The check box “Clamped” does not affect on exporting resoults at all.

Resoults in QGIS and settings of a Classification in PIX4D Mapper Index Calculator:

Hi,

I reproduced same 10 zones with equal spacing and got 10 zones on the prescription.
Would you mind uploading your NDVI orthomosaic and shape prescription here Error
So I can see what could be wrong.

Best,
José
