Inkscape's double lines when cutting

[woodcraftlodge]

Hey guys I was wondering if anyone could point me in the right direction with this one. I’ve been trying to figure this out and I just can’t hack it.
Here’s my issue, for some reason now when I upload a vector image and try to cut the borders, it appear double (One line on the outside and one on the inside). I’m pretty sure it could be from the thickness of the lines but when I tried thinning them out I was still left with double. I’ve cut images before so this is kind of out of the blue for me. If anyone can help thanks!

Avoiding Double Cut Lines In Your Designs

Avoiding Double Cut Lines in your Designs.pdf (525.8 KB) Note for Adobe Illustrator users: Watch that you always place the stroke in the center of the path (not either inside or outside the path) because the newer versions of Illustrator automatically Expand those when you create your SVG file. (The older versions didn’t.) Just check the Stroke style, and make sure it is centered on the path.
