Ciphers list '' for profile /Common/SSL_Test denies all clients

Hi folks,

Need help in configuring custom ciphers to attach to the SSL profile. I've configured the Cipher rule with following ciphers and then created Cipher Group.

ECDHE-ECDSA-AES256-GCM-SHA384:

ECDHE-RSA-AES256-GCM-SHA384:

ECDHE-ECDSA-CHACHA20-POLY1305:

ECDHE-RSA-CHACHA20-POLY1305:

ECDHE-ECDSA-AES128-GCM-SHA256:

ECDHE-RSA-AES128-GCM-SHA256:

ECDHE-ECDSA-AES256-SHA384:

ECDHE-RSA-AES256-SHA384:

ECDHE-ECDSA-AES128-SHA256:

ECDHE-RSA-AES128-SHA256

when I am trying to add the Cipher group name to SSL profile then it gives the above error.
