Welcome to our Community @Tjsdman! Thanks for stopping by! I'd like you to know that at the moment there's not an option in the Fitbit Dashboard to block a person you don't want to see however, with the information you provided in your post I believe that a possible reason for you not being able to see this person is that maybe he/she decided to not be visible to other people in Fitbit. You can do this by changing your Privacy settings on your online Dashboard.
Hope this helps! Have a great week!
