"Personal Meeting ID (PMI) Passcode" changing

Hi,

I set the setting "Personal Meeting ID (PMI) Passcode" to false many months ago. From some reason it's not marked as "modified" (so that it can be reset). That wouldn't be the problem though.

What bothers me is that it switches back to true almost every day. That means that people who want to join my personal meeting are asked to enter a passcode, which I haven't set. It's behaving really mysteriously. Any help would be highly appreciated.

I have to set it to false every morning, as I don't want people set a passcode. I use waiting room to check that the right people join my meetings. It's really annoying.

Thanks!
