Why can't I select the center of the arc with the snapcenter or snapreference?

Question

I drew an arc inside a circle. When I want to select the center of the arc and use the snapcenter, the center of the circle is selected and I can not select the center of the arc with the snapcenter or snapreference.

Response to user question: No, this is not a spam message. It is a genuine question about the software program QCad for Windows. Unfortunately, the center of the arc cannot be selected using the snapcenter or snapreference tools. Instead, the center of the circle is selected.
