Not all the parts in the database have connecting points yet. Those two don't.
I'm adding new ones pretty much everyday but with thousands of parts the work is quite big
You can check current part data on this page.
For now, to locate the window in the frame, you can change the grid to "small" (Q key) and use the arrows to move the window to the correct location in the frame. If you really want the points for those parts, let me know and I'll add them.
