Not able to edit custom fields "404 not found error"

I am able to edit some but not all of the fields in the "custom fields" area of GeoCraft. When I click to Save the options I've chosen, I just end up with a 404 page.

Almost all of the social media custom fields land me on a 404 when i try to update them. My site is pdxbusinessdirectory.com

One strange thing of note: When I go to the custom fields section of my site, the header reads:

Custom Fielddfdfd Options
