How do I remove old invalid addresses from autofill in Messages app on Mac?

I am having trouble with autofill in the Messages app. When I try to send a message, the autofill suggested a list of messages that included old invalid addresses. The old address were green colored. The current ones are blue colored.

My iPhone and iPad does not have this issue. They suggested data from my Contacts.

I have tried cleaning cache, restarting, etc.

I can't find where the green messages are stored to clean them out.

I am using a M3 iMac with Tahoe 26.1

Any help would be appreciated.
