Apache Extension Error

I have an Apache 2.4.18 with OpenSSL 1.0.2f configuration here with dual (RSA 4096 + ECC 384) certificate configuration. I also provide certificate transparency through TLS extension.

When using openssl s_client -serverinfo 18 -connect winpack.cf:443 to test my Signed Certificate Timestamps, openssl uses the EC-384 certificate and everything works (TLS extension 18 is correctly provided).

However, when running openssl s_client -cipher 'ECDHE-RSA-AES256-SHA' -serverinfo 18 -connect winpack.cf:443 to force use of RSA-4096 certificate, the extension is NOT provided and the output is as follows: (you can run it too, you will have the same results… I tried running it from 3 computers of different subnets)

What may be going on here?

        #   Point SSLCertificateChainFile at a file containing the
        #   concatenation of PEM encoded CA certificates which form the

        #    Translate the client X.509 into a Basic Authorisation.  This means that
        #    the standard Auth/DBMAuth methods can be used for access control.  The
        #    user name is the `one line' version of the client's X.509 certificate.
        #    Note that no password is obtained from the user. Every entry in the user
        #    file needs this password: `xxj31ZMTZzkVA'.
        #   o ExportCertData:
        #    This exports two additional environment variables: SSL_CLIENT_CERT and
        #    SSL_SERVER_CERT. These contain the PEM-encoded certificates of the
        #    server (always existing) and the client (only existing when client
        #    authentication is used). This can be used to import the certificates
        #    into CGI scripts.
        #   o StdEnvVars:
        #    This exports the standard SSL/TLS related `SSL_*' environment variables.
        #    Per default this exportation is switched off for performance reasons,
        #    because the extraction step is an expensive operation and is usually
        #    useless for serving static content. So one usually enables the
        #    exportation for CGI and SSI requests only.
        #   o OptRenegotiate:
        #    This enables optimized SSL connection renegotiation handling when SSL
        #    directives are used in per-directory context.

        #   SSL Protocol Adjustments:
        #   The safe and default but still SSL/TLS standard compliant shutdown
        #   approach is that mod_ssl sends the close notify alert but doesn't wait for
        #   the close notify alert from client. When you need a different shutdown
        #   approach you can use one of the following variables:
        #   o ssl-unclean-shutdown:
        #    This forces an unclean shutdown when the connection is closed, i.e. no
        #    SSL close notify alert is send or allowed to received.  This violates
        #    the SSL/TLS standard but is needed for some brain-dead browsers. Use
        #    this when you receive I/O errors because of the standard approach where
        #    mod_ssl sends the close notify alert.
        #   o ssl-accurate-shutdown:
        #    This forces an accurate shutdown when the connection is closed, i.e. a
        #    SSL close notify alert is send and mod_ssl waits for the close notify
        #    alert of the client. This is 100% SSL/TLS standard compliant, but in
        #    practice often causes hanging connections with brain-dead browsers. Use
        #    this only for browsers where you know that their SSL implementation
        #    works correctly.
        #   Notice: Most problems of broken clients are also related to the HTTP
        #   keep-alive facility, so you usually additionally want to disable
        #   keep-alive for those clients, too. Use variable "nokeepalive" for this.
        #   Similarly, one has to force some clients to use HTTP/1.0 to workaround
        #   their broken HTTP/1.1 implementation. Use variables "downgrade-1.0" and
        #   "force-response-1.0" for this.
