Strange issue with getting Wrong Text Message ID on Apple Watch

watchOS & Apple Watch Apps

Hello everyone. I have a bit of a mystery I am trying to solve. If you have any ideas as to what is causing this, please share in the comments.

It's probably not an important detail but my parents have the same last name. When my mom texts me. The message ID on my Apple watch shows that it is from my dad, not her. But, the notification shows that the same message is from her on my iPhone. There are no anomalies when my dad texts me, and, this doesn't seem to happen when my mom texts anyone else who has both an Apple watch and an iPhone.

Do you have any idea what could be causing this?

Thanks in advance.
