Zonal histogram seems to be stretching values

The values of pixels in the original raster range from 0-63. However when I make a histogram (Zonal Histogram), using a shapefile as my input zones, I get a distribution of values from 0-255. Any idea how this is happening? How can I ensure that the values are from 0-63?

Any help would be appreciated.

Thank you.
