Blue Numbers pop up on Email

I have been noticing when I go to delete an unopened email from my inbox - quickly shows a number in a blue dot then it disappears. Duplicate emails also if I delete one the other goes with it ??? Curious

My Norton keeps showing also that IP addresses keep disappearing too.  Anyone having these types of situations??

They sort of started when I started taking surveys. Pretty much eliminated cookies and tracking but cannot get rid of Opinion Square.

Thanks everyone!
