preferred_chains not consistent after auto renew

[JaosnHsieh]

Since the issue on electron.
Remove the current certificate by $ rm -rf /var/lib/caddy/.local/share/
And add ISRG Root X1 as preferred_chains value and issued ISRG Root X1 certificate successfully.

But after around 2 weeks, Caddy automatically renew the certificate, and seems like it's not use ISRG Root X1 as preferred_chains.

Is there a way to check what's the preferred_chains value in existing files in /var/lib/caddy/.local/share/ or how to make it consistent after renewing?

OS Ubuntu 18.04
Caddy version 2.4.5

/etc/caddyCaddyfile

api.example.com:80 {
        reverse_proxy localhost:3333
        tls {
        issuer acme {
            preferred_chains {
                root_common_name "ISRG Root X1"
            }
        }
    }
}

api.example.com:443 {
        reverse_proxy localhost:3333
        tls {
        issuer acme {
            preferred_chains {
                root_common_name "ISRG Root X1"
            }
        }
    }
}

After checked issue history from https://crt.sh/.
It seems not related to renew issue on Caddy.
closed because the issue should on electron side.
