I didn't notice it listed as a limitation of the Sandbox... <a href="https://wiki.roll20.net/Custom_Sheet_Sandbox" rel="nofollow">https://wiki.roll20.net/Custom_Sheet_Sandbox</a> While I can edit the sheet.json and see those changes applied to new sheets, I'm not able to apply those changes to existing sheets if I also use the "Apply Default Settings" option from the sidebar.&nbsp; Maybe this only works once the sheet is live?
