@lu-menard in your Settings I still see that you have "When a new reply is posted in a topic you are watching" set to "Notification & Email".
Additionally you are watching some topics, including this one, for example, so it's to be expected that you'll get an e-mail about this reply that I am just typing, for example.
Can you please confirm that you tried to change "When a new reply is posted in a topic you are watching" to "Notification Only" and it didn't work? If so, did you remember to click the "Save Changes" button at the bottom of your Settings page?
Finally what happens when you refresh your Settings page after the change?
