Hey Olivia,
Thanks for reaching out to us!
I’ve tested this based on the instructions you’ve provided but wasn’t able to replicate the issue. I was able to see the content on the front-end of the site. I then went back and refreshed the setting page as well as re-navigated to the settings page and both times saw the content still saved within those settings.
As an initial step, would you mind following the Testing for Conflicts procedures to ensure there isn’t a conflict here with an existing plugin or theme?
Let me know if those steps reveal any additional information.
Thanks!
