Can someone talk some sense into me. I used DH phone to send myself an image on whatsapp while sat next to him. Happened to see the name of most recent messages sent to as its right there when you send a message. A few mins later I went to send something else and this name had gone from the list. I checked as couldn't help it at this point and he has no messages sent to this person at all. That makes no sense to me as the whole point of the whatsapp list is that its the most recently sent to the most list. Worst thing is the name was someone of the same sex, not even in his contacts. Can someone explain this to me or should I be concerned?
