iPhone HELP !! OLD MESSAGES and NUMBERS

[IGWT15]

Hello folks,

I have public beta 6 installed on my iPhone XS Max, but how do i delete old iMessage contacts and numbers that I have messaged in the past? I've noticed that if you go to the create a text message button, and then you type in the @ symbol, all these old numbers and contacts names that I don't even have on my contacts any longer pop up, and I have no option to delete them, does anyone have a solution on how to delete these old no longer existing numbers and names?

Just updated to beta 7 and the issue continues, I wonder if I’m the only one experiencing this issue? Please let me know. Thanks

Old contacts and phone numbers continue to appear when starting a new text message. Anyone experiencing this? And if so how do I delete these old names and phone numbers from appearing? We are just 2 weeks away from the GM. Is this going to be fixed?

Thanks again
