All users are assigned with moderator roles in updated jitsi-meet

We have installed jitsi-meet-2.0.4468-1(stable) in a Cluster of 4 VMs with Debian Buster:

  1. VM1 hosts: Jitsi-Web, Prosody and Jicofo
  2. VM2, VM3 and VM4 each host Jitsi-Videobridge-2

The problem we noticed that each user after authentication is assigned with moderator roles. In previous version this was not the case, the previous jitsi-meet version the first user was moderator.

Can anybody help with this issue?
I would also like to know that is it possible to have only one moderator as first user and update to other user if moderator quits a meeting.
