Menu edits not changing even after clearing the entire Wordfence cache?

Hey folks,

I have enabled WPMUDEV dashboard support just now.

The menu item links in the dropdown menus are not changing. We have even done complete clearing the entire Wordfence cache.

I want to temporarily remove Donors from the About Us drop down menu. I tried removing the parent, but nothing changed.

I also want to change the URL at the Take Action > community conference.

It currently reads community-conferences-2 and I want to change it to community-conferences.

Seems simple enough but changes are not be seen on the site.

Do you have any ideas or thoughts to get the changes to start appearing?
