I also had the same problem ... It was my solution ... You go to contacts on your motorcycle c, select contact, on the top right (EYE) select the small pen (edit), without editing anything of the contact select on the top right the small three points ... And select "UNLINK", ask if you are sure, select yes or unlink ... Appears contact message unlinked and ready ... Now you can search for the same contact select it go to three points from the top right and delete ... I hope it helps, it served me very well greetings
