That's working as intended. The survey won't accept you wanting two things most or least. You can pick one you want most, one you want least, and the unselected option is the one you have the weakest opinion on.

That isn't a break. They are forcing you rank them by most, least, and between.

Of each set of 3, you can only have one marked as most wanted and one marked as least wanted. You will leave one statement blank.

You Should reach out to them and let them know of this glitch.

I don't think you understood the assignment friend.
