Jon, if you open the "Changes" tab, you will see no record that anyone made a change. When changes are made on the edit page, we scroll down to the bottom of the edit screen where we can click "Preview" to be shown what the changes will look like. Nothing will be saved until we click on one of the two "Save Changes buttons".
Try editing the profile again and let me know the outcome. And while your at it, please enter something descriptive in the data field titled "Explain your changes; ---before saving.
Pressing the F5 key reloads the page that was edited onto your computer to display the new/replacement document residing on the WikiTree site. The new page will only exist on the site if it was saved to the site.
