On sending a text message to myself on iPhone 14 Plus it triplicates

For a while now every time i send a text message to myself on IPhone 14 Plus it shows up in triplicate.

How can I fix that? IOS is updated to 18.5. I have turned it off and rebooted but nothing works.

it’s very time consuming to have to delete all those messages all the time.

please help.
