How to delete invalid recent Messages Macbook MacOS

Does anyone know how to remove a recent entry from showing in on the MacBook Messages? I have removed the contact completely from iPhone, iPad, MacBook Air, Contacts, Outlook - the contact is gone completely. The problem is I entered the wrong number when I first created the contact and I cannot get rid of that wrong number from showing in the recent list on my MacBook Air. It does not show on my iPhone in the recent list, only on the MacBook Air. When I type in the name the person comes up with both the wrong number and the good number (even though contact has been removed). I simply need to remove the wrong/invalid number from the recent list in Messages App on the MacBook. It has been removed from the iPhone, I have turned off iMessages on the MacBook, shutdown, restarted, made it inactive/re-activated, all to no avail. I cannot get the recent invalid number to go away. I have read others have the same issue but haven't found a solution online so hoping someone here has a solution. Thanks.
