FreePBX hooks not exporting endpoint dtls related data

Hello,

After a fpbx box update (also couple of fresh installs) i am facing a dysfunctional behaviour of freepbx core (precisely gen config).

First i noticed our endpoints not being able to answer calls (Failed to execute ‘setRemoteDescription’ on ‘RTCPeerConnection’: Failed to parse SessionDescription. a=fingerprint:SHA-256 Failed to create fingerprint from the digest.)

No hash is visible after "a=fingerprint:SHA-256".

I am using SIPJs webrtc clients.

I concluded that Freepbx does not export dtls parameters of the endpoint (pjsip.endpoint).
I checked that Media Encryption is set to DTLS-SRTP, DTLS is also enabled.
Still these variables are not generated : 
40 => “dtls_verify=fingerprint”
41 => “dtls_setup=actpass”
42 => “dtls_rekey=0”
43 => “dtls_cert_file=/etc/asterisk/keys/XXXX.crt”
44 => “dtls_private_key=/etc/asterisk/keys/XXXX.key”

I traced some of the admin scripts , Certman.class.php is getting the data correctly , and is successfully setting the PJSIP class "_endpoint" array attribute via dialplanHooks.
But later it gets cleared right before Languages class is editing the attribute(_endpoint).
The variable ends up containing only language parameter, which explain why PJSIP Hook genConfig doesnt export the dtls variables.

I tried hosting my b2bua on different datacenters, different asterisk versions, new domain/certificate, OpenSSL 1.0.2k-fips upgrade to openssl 1.1.1, no success.
