Can't delete text link on one of my pages

Site URL: http://www.smeltzercartoons.com/#/1997-sweetwater-music-calendar-cartoons/

I have a line of linked text in what I think is a footer on one of my pages. The text is: "Back to Business Cartoons | Family Cartoons | Doctor, Teacher and Veterinary Cartoons by Steve Smeltzer". Also, next to that line of text are the links that say: "prev/next"

I select edit, but can't select or delete any of those words. 

I'll include a screenshot.

Any ideas what I'm doing wrong?

Thanks,

Steve
