Bruce is correct. In half-filled orbitals (with only one electron), electrons with spin "up" should be positioned on the left, while those with spin "down" should be placed on the right.

Another detail - probably needs input from Jorge - at the moment if there is a single electron, the arrow is centred in the box. Would it help to have an option that up arrows align left and down arrows align right so that there is a space where the missing arrow would go?
