links will not update on site

Site URL: http://www.aiylc.org
WordPress Version: 4.7.2

I have updated and tried to save the links on the site to point to their correct files/pages but they won't update.

For example the application link is supposed to link to:
http://www.aiylc.org/wp-content/uploads/2017/02/AIYLC-2017-APPLICATION.pdf

and it keeps pointing to:
http://www.ailyc.org/wp-content/uploads/2014/10/AIFCV-Application-2016.pdf

which is the old file thath as been deleted.

I have support access turned on for the site.
