adobe illustrator - There is a line in the middle of my stroke. How do I fix that?

I am trying to make a circle with dash but there's a black line that wont go away.

How do I fix this? I have looked through the appearances tab. I have also tried deleting that object then redoing it but, nothing has worked. It is one single image that has three strokes on it. It might just be a glitch in my program.
