Deleting Calendar invitee suggestion
When I create a new event and add invitees, I often get a suggestion for a person I do not know. This person is not in my contacts. I don't appear to have any email from them. I must have had contact with them at some point but I don't know who they are, nor do I expect I will have contact with them again. Unlike with Mail, where you can simply delete suggestions, right clicking/deleting does not work.
I have Googled this and found lots of people with the same issue, but have not seen a solution. Picture below for clarification. Julian (JJ) is my husband who I want to be the first suggestion.
