I have an original listing Les Guittieres Gite and need to add a new one correctly

I have an original listing which was Les Guittieres Gites , i thought i had added a new listing which is The Glade Bell Tent. However the main heading is now Les Guittieres, when you click availability Les Guittieres Gite and The Glade have a calendar each. but somehow people are seeing pictures of the gite and booking it under the glade thinking its the same thing, only photos of the gite show when you search booking.com. Please help ive now had two bookings for the Glade but actually they wanted the gite. Ive cancelled one but the other is through booking.com .Can you please help me get these listed seperatley ?
