Your filter gallery shows that you are applying not one, but two filters at the same time. Conte crayon or Granulosita AND Pattern Mezzatinte. Uncheck the eye icon on that second filter to see the impact of just one (you can also highlight the unwanted filter in the filter layers and click on the bin to remove it).
Note also : Some filters are shown as black and white. In actual fact they use the current foreground and background colours - so make sure you set the foreground and background to black and white before using them (press D) unless you want specific colours.
