ELBSecurityPolicy-TLS13-1-3-2021-06 is the correct policy that only supports TLS1.3 https://docs.aws.amazon.com/elasticloadbalancing/latest/application/describe-ssl-policies.html#tls-security-policies

I have just tested this and I only see TLS1.3

Try and use https://www.ssllabs.com/ to check

Just double check you have selected the correct policy and left it a few mintues to apply the change
