Why won't my FaceTime calls show in my most recent calls in phone app

Hi, every time someone FaceTime me or I FaceTime someone it does shows up in the FaceTime app, but when I go to the Phone app and go to most recent, it’s not there. I would like to check how long my calls are and when I click the information card in the FaceTime app, it does not show how long it was. But I would just really like them to show in the most recent in the Phone app and how long the calls was. Can someone please help me.
