Unique Jitsi meet link shows 'Fellow Jitser'

Hi , We created a unique link for a jitsi meet. When the participants (2) joined, they saw 3 more participants marked as Fellow Jitser. Even though hovering over their network profile showed N/A for bit rate etc, it was concerning for the participants to see extra users on the meet. Can someone help me understand what could be the issue here and if there is a fix to resolve the same.
