GCM cipher suites are enabled but not discovered by SSL Labs test
You show various *ECDSA*GCM* ciphers as enabled. But these are all cipher suites which require an ECDSA certificate, i.e. with an ECC public key. My guess is that you instead use the more common RSA certificate which means that no ECDSA ciphers can be used. Instead you would need to enable *RSA*GCM* ciphers, for example TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256
