i am having issue with mapping domain in google cloud platform so i have just verified my domain but then i am having this issue 
but the thing is that i have not added my domain to my project yet as you can see below in picture
so i have not added "w3youtube.com" to mapping or created any dns records but still i am having www.w3youtube.com is already mapped to a project.
what should i do? in order to remove mappings or to resolve this issue?
