Dotted line after Path tool

[Snowy]

Hi, Im new to gimp and have been learning it. I was cropping out a plane for a photo and i used the path tool. After I pressed enter and inverted the image and removed the background, I noticed this line and it never disappears. How can i remove it?

This is the selection. You can make it no visible (View>Show selection or Ctrl-T) or completely cancel it (Select>None).
