Listing as Private Room INSTEAD OF Entire Apartment

[Ashaki--Saki-0]

Earlier a friend was having diffiuculty finding the space.  We've deduced that it is no longer listed as Entire Apartment but Private Room  and so when that filter was applied, my apartment didnt appear.

(which is strange because it was NEVER a Private Room...its a Studio Apartment...Entirr Apartment or nothing).  

I AM HAVING DIFFICULTY CHANGING THIS FEATURE.  How can I change my listing back to "Entire Apartment"?
