Fuji-Excursion limited express tickets

I would like to buy online limited express Fuji-Excursion tickets on Ekinet, but I’m not sure what sould I do when I pick the tickets.
I just send you a picture, It will be easier what my problem is.
Below the text should I mark that sentence or not?
I’m not sure what does it mean.
I would like to buy 2 tickets for that train. But if I mark that sentence the amount of money will change.
Should I mark that sentence:
, Purchase tickets such as the Super limited express train ticket only.‘’?
