UV editing/mapping problem

Hi guys,

I’m new to 3d animation and blender. I’m following the blender donut tutorial of the blender guru to get started and learn the basics. However I face a problem when I try to UV unwrap my mesh of the coffecup. Could someone explain whats going on? I attached a picture of the cup, my UV unwrapping and how its supposed to be.

Hope you guys can help me!
