Hi @moettinger
You should be able to export the JSON file from “Custom Fields > Tools”.
Also, it seems your WYSIWYG field somehow has the Show Media Upload Buttons? set to empty, which makes ACF thinks that it’s set to false.
To fix it, could you please expand/open all WYSIWYG fields in your flexible content field on the field group editor page and then resave it. You don’t need to change anything, though.
Hope this helps 🙂
