Inaccurate Screen Time Message Notifications

My iPhone screen time data is showing inaccurate message notifications. I received 4 text messages total one day and when I checked my message notifications in screen time, it showed 7 message notifications for that day. I double checked and counted all of my text messages to make sure I did not miss any text messages, but there were still only 4 text messages that I had actually received that day. I’m not sure if this means there are 3 missing text messages or if there are other notifications that count toward the metric on notifications for messages.
