Not Found Page is rendered after clicking on hyperlink to on page anchor

Hi,
I'd requested and received assistance in creating an anchor in Upfront. I followed the instructions and created the anchor element; then I created a hyperlink to it. However, when I tested the hyperlink after saving the page and exiting out of the browser in which I have wp-admin open, the link takes me to No Page Found with a URL of http://blackmothersunited.org/edit/page/2267#eligibility

Because I don't want this to happen to a user, I have deleted the hyperlink from the word "eligible" on the http://blackmothersunited.org/our-events page until this can be resolved. I've attached a document with screen shots of the issue.

I've given access to you to the site and look forward to hearing from you soon.

Thank you in advance for your help!

Sincerely,
Kimberly
