Meetings and Webinar grayed out

This is a good one. I have a user that the Settings > Meetings and Webinars setting for dual monitor is on and grayed out. Unfortunately the user want it to be on tabs and not dual monitor.

The user has multiple monitors but even disconnecting everything from the laptop it remains grayed out. There is no admin policy for this and its local.

Has anyone come across a solution for this? She I go back to an older version for the user and its a bug in the latest version?
