Text message app sending strange text messages

[cinque8]

Hello,

I have a Nokia 3.1 phone running Android 8.1.0. My phone uses the default Google Messages app to send and receive text messages. The Messages app was working perfectly until recently. I was a recipient of a text message sent to about 6 people. When I replied to the message that was sent, all of the other recipients received a private text message containing my reply, as well as my reply being in the original mass text message. This has never happened before. Can anyone tell me why this is happening and how I can fix the problem?

Thank you
