What could be causing my inset to act as 2 areas instead of 1 as the video shows? I believe I have selected the same faces as in the video, but when I inset I keep getting 2 insets -- 1 upper and 1 lower area. Do I possibly have extra vertices or edges that I can't see? I've select around each vertice, but merge vertices isn't an option when I right click, which makes me think there are not multiple vertices.
