Circular pattern sketch inside hole wizard feature

Hi everyone, I'm new to Solidworks and forum.

I dont know if this is a bug or that's the way it is, but i hope somebody can help me out.

On a surface of a part, i want to create a circular pattern of holes. After I specify my hole size and type, I position the first hole vertical from the origin at a distance. Then, i use circular pattern sketch to create 7 more holes around the created construction circle.

But besides those 7 holes, an extra hole also appears right at the center of the circle, I tried many ways but still could not get it goes away. This behavior only happens when circular pattern is used inside hold wizard feature. Normally, circular pattern sketch does not create a copy at the center of the circle(correct me if i'm wrong).

In comparison, circular pattern feature works fine with patterns. I'm just curious why circular pattern sketch behaves differently while inside hole wizard feature.

Thanks
