Having custom TLS config in tls.cfg, RPC `tls.options` seems to report default settings. Bug or intended?

root@kam:/# kamcmd version    
kamailio 5.3.2 (x86_64/linux) 0bed10

root@kam:/# kamcmd tls.options
{
 force_run: 0
 method: TLSv1
 verify_certificate: 0
 verify_depth: 9
 require_certificate: 0
 private_key: /usr/local/etc/kamailio/cert.pem
 ca_list:
 certificate: /usr/local/etc/kamailio/cert.pem
 cipher_list:
 session_cache: 0
 session_id: kamailio-tls-5.x.y
 config: /usr/local/etc/kamailio/tls.cfg
...
}

modparam("tls", "config", "/usr/local/etc/kamailio/tls.cfg")

root@kam:/usr/local/etc/kamailio# cat tls.cfg
[server:default]
method = TLSv1.2+
verify_certificate = yes
require_certificate = yes
private_key = /tmp/privkey.pem
certificate = /tmp/fullchain.pem
ca_list = /etc/ssl/certs/ca-certificates.crt

[client:default]
method = TLSv1.2+
verify_certificate = yes
require_certificate = yes
private_key = /tmp/privkey.pem
certificate = /tmp/fullchain.pem
ca_list = /etc/ssl/certs/ca-certificates.crt

Cheers.
