Fill Tool is not working

I am trying to fill the depressions. However it seems fill tool is not working, since cut fill generated raster file is displaying zero for all volumes. In addition when I am applying sink tool over the filled DEM, I would end up with the same number for unfilled DEM, Although I have to expect zero for the number of sinks after filling.
Note that the surface I am working with has a high slope of 13%
Any recommendation on why the fill tool is not working?
