Help with Calendar Sync

Hello, I have 1 property with 3 rooms

Each room has it's own type. So there is no room type with multiple rooms available.

The Sync Calendar option is not appearing under Calendar - Rates & Availability.

I had no problem setting this us with my other property and this is critical so I dont get double bookings.

What do I need to change so this option appears?


Thank you


If you go to calendar,  list view, and review each room, does any have an inventory count greater than 1 where there is no booking?
