Pen tool is cutting off my image

[SunflowerMindGoat]

Hi, I am new to illustrator and am taking a class online. No one really responds to the class anymore and I don't want to wait and see if I get a response. I was wondering if someone could help me here. I am learning the pen tool and how to use it we are tracing an image of a cat. Below is how is started tracing the image but when I get to the nose part and try to make a curve, it is cutting off the orginal image and is making a whole new image. How do I get this to stop? In the video from the class it wasn't discussed and I would really like to know how to fix this. If you need more clarification please let me know.

hmmm, this can't be a fill.

Does this look better when you go in CPU preview mode?

How do I get to CPU preview mode? I am new to Illustrator and am just learning, If you could explain more that would be helpful.

You can find it in View > Preview on CPU

If that does not solve it, please open Window Appearance for the selected path and show a screenshot.

It did not work, I attached the image for you.

Your image is invalid. Can you please embed it into your post?

I figured out the issue, my fill color was set to white instead of set to none and then having the stroke. I apprieciate you trying to help me.

Looks like you are tracing with a white fill.

Can you set it to none in the Tools or Color panel?
