Hummingbird helix trail clutter

I purchased some lake Palestine trails from a local guide and after loading them on my helix 7 they are all connected to eachother with straight lines going all over the place making it impossible to safely see the actual trails. I'm using the free hummingbird chart software. Does anybody know how to fix this?

Mine did the same thing. I'm not for sure you can, but I'm curious if anyone knows for sure.
