Some sections of my listing have mysteriously been deleted !!!!!

[JC4]

I happen to check my listing today and the following sections are empty:

-The Trip
Guest Access
Interaction with Guests

-The Neighborhood
Overview
Getting Around

I know for a fact I DID NOT delete these sections, anyone else has experienced this? Why did this happen?

@JC4 Do me a favor and go to your Account Settings.  Check your Notificaton Settings and Security Settings especially your Login History.  Anything unusual there?  Get back to me.
