Can't find Export button of calendars


I would like to Export the calendar of my offered rooms to Airbnb and also my website. I checked manuals, tutorials and it's supposed to be located in: Rates & Availability -> Calendar - Here I have list of offered rooms but no Export or import buttons, not even inside buttons like "Bulk Edit". 

Can someone direct me, please?


How many rooms of same type do you have set?


Example if you have double room and count is 2 or more you wont see these options. Reducing the count to 1, and then add each room as a different unique room is the only way that feature appears I had the same issue previously. 


Kind regards, merry xmas
