iMessage on phone show “delivered” but iMessage on MacBook air shows “read”?

I sent a “bundle” of three short iMessages to someone two days ago. My MacBook Air shows that the three messages were “read” but my iPhone 7 shows that the three were only “delivered” but the messages before them were "read." Today, a “read” with a specific time showed up under the first two messages of the bundle as if they were “read” today but there’s still a “delivered” at the end of my last message. Does anyone know why this is happening and how to fix it? Both my laptop and my phone are up to date regarding software.
