Unknown numbers being added to a group message

Good morning - this has been happening to me in a group with my siblings. They get removed from the chat and random numbers get added! I'm using a Galaxy S22 Ultra and I have a Samsung watch with a plan paired to this phone. 

Wondering if you have the same device and/or a watch paired to your phone too?

I have a feeling it could be the watch phone number belonged to someone else before me, and maybe the numbers being added are from an old chat it was a part of or something like that.

 

Here's an example. Rob and Mark are my siblings. None of us invited these random 719 numbers to the group. When they 719 numbers joined, my brothers both suddenly 'left' the group - were removed. When I texted back to the group to ask who the 719 numbers were, my brothers came back and the 719's left…  it's very odd and disconcerting that some random phone numbers ended up in my group chat with my family, and could potentially see the history as well.

 

The same thing just happened to me my siblings were kicked out of the group and they were added in and a month ago 2 random numbers were added in and it said I added them when I never did idk how this keeps happening
