When adding text to a hole note that has dual dimensions the text will appear twice if the "Edit Hole Note" dialog box is used. To only have the text appear once the “Format Text” dialog box needs used. If you are in the “Edit Hole Note” dialog box you have to exit it and then select the “Format Text” dialog box. It would be convenient if the “Format Text” dialog box could be accessed directly from the “Edit Hole Note” dialog box, similar to how there is a “Text” tab in the “Edit Dimension” dialog box.
Same thing for "Edit Chamfer Note"
