My phone has started randomly dialing people on my favorite list as soon as I hang up

Something truly irritating has been happening lately. When I’m speaking with someone then hit “end call”, I’ll look down and see my Phone is dialing out to the second from the bottom on my favorite list…. This has happened 6 times today. It’s so irritating … it’s like the favorite screen is up… call comes in, and when I hit end (bc it would about line up where that person’s name is) it also clicks their name to call…. My short fix is that I have deleted the last two names from my favorite list…. Is anyone having this issue?
