Hello @Jozie2
So in host mode go to:
==>Listings
==>Click on the cover photo of your listing that appears
==>From the photo tour on your right, click on the bedroom
==>Just under the photos of the bedroom, you'll see Sleeping Arrangements click and change the double bed to zero and add plus 1 for the Queen size bed
==>Also have a look at Amenities in this section too which allows you to tick what is offered in that bedroom. Ditto for all the other rooms you've created.
Hope this does the trick😊
