I was editing the layout of Accounts -> DetailView with the Studio editor, and decided to revert to the default view by pressing “restore default”. Now, whenever I make changes to this particular layout and press “Save” or “Save and deploy”, my changes disappear and everything reverts to the default view.
I have tried various repairs in the admin menu, but none have worked.
I have replicated the error on several other pages. All changes will work as long as “Restore Default” is never pressed on that page.
Screenshots are attached
