I've noticed that the appearances of many characters can be sorted by publication date. However, not everyone has this option. (For example, Nick Fury Sr. of Earth 616 cannot have his appearances sorted this way, but the individual founding New Warriors can.) Does anyone know why this option isn't present for everyone?

Secondly, there are some issues that do not have publication dates when sorted, but which do have such dates when viewed as an individual issue. Again, does anyone know why that is?
