Certain Cipher suites are not shown in ssl server test

Yes, they are properly assigned. When I change the CIpher rule which is:

TLSv1_3:ECDHE_ECDSA+AES-GCM:ECDHE+AES-GCM:ECDHE+AES:ECDHE_ECDSA+CHACHA20-POLY1305:ECDHE+CHACHA20-POLY1305:!DHE+AES-GCM:!TLSv1:!TLSv1_1:!ECDHE+AES:@STRENGTH

I see differencies when checking the ciphers but only ECDHE_ECDSA are not visible into the ssllabs.

I even tried with openssl and sslscan tools via linux and didn't saw it as well....

I just found out the reason. The certificate is created as RSA. which means :

RSA: Specifies that the key is based on the RSA public key encryption algorithm.              

So no ECDSA will be presented even allowed in the cipher suite....
