Adding a sketch circle on the center of the existing circle

I am not sure if this is a bug but it looks like when you start a sketch and add a circle then stay in the circle command and add another circle to the existing center point it keeps saying “locked point can’t be moved” which I am not trying to move I am just trying to add a new sketch circle to a existing center circle. Same thing happens with adding center point rectangle. It works fine if you get out of the command but I remember that before you never had to get t of the sketch command. Let me know what you think.

Thank you
