You need to set the WindowStartupLocation to Manual (which is the default however) as well as setting the Top and Left property values.

Setting CenterScreen causes a window to be positioned in the center of the screen that contains the mouse cursor.

Setting WindowStartupLocation to CenterOwner causes a window to be positioned in the center of its owner window (see Owner), if specified. The owner window can be either another WPF window or a non-WPF window.
