New Suggestion
When editing the settings for a pop-up, the fields should be saved after editing, OR the "save settings" button should clearly apply to the entire page.
After editing a field, it looks like maybe the field saved (similar to other settings screens), but on navigating away from the configuration screen, changes revert. Changes are only saved after clicking "save settings" button which visually looks like it only applies to the "Content" card.
Move the "Save Settings" button so it clearly applies to all of the panels on the page. Ideally it should also be visibile without scrolling so I know I need to click it to save my changes.
Or, make this section behave like the majority of settings and save each field after editing and only have the "Save Settings" apply to the content portion
