Unlike the other page type, Profile Pages do not automatically refresh their page previews which leads to the misconception that changes do not save.
For the changes to show, you would have to regenerate your Profile Pages. Here's how:
01. Click on the Pencil icon
Clicking on the Pencil icon loads the Profile Page setup. To start regenerating your Profile Pages, click on Review Responses.
02. Generate Profile Pages
After clicking on Review Responses, all the Profiles will load. Click on Generate Profile Pages and then on Yes generate new pages. This should regenerate the Profile Pages and should show the changes that you made as well.
