Trust certificate

I have changed the trust option in my keychain to trust always, but on my email account in Mac Mail, there's a little squiggle and when I click on the squiggle to look at the certificate it says "when using this certificate Use System Defaults. How do I change that?

2 certificates have just been renewed and it's these ones which are causing the problem.

MacBook Air 13″, macOS 12.1

Oh n it hasn't. When it first came up they all showed OK but within seconds I had the message saying they were unsafe, and when I clicked on the certificates it still says they are using system defaults.
