I am new to Blender and I´ve decided to watch Blender Guru´s video on how to make an anvil. I´ve come to the second part where he uses a boolean modifier and that´s where my problem appeared. When I use the boolean modifier to curve a cylinder shape into the anvil it also deletes the faces which in the video it does not. I think I followed every step so I can´t really tell where I´ve made the mistake but I can´t find a solution.
Here´s a link to the video: https://www.youtube.com/watch?v=WxMwa0njGSM

Thanks for help.
