in config.yml, I have the following ``` fields: - { label: 'Path', name: 'path', widget: 'hidden', default: '/book/{{title}}', } - { label: 'Title', name: 'title', widget: 'string', required: true } ``` the generate markdown has `path: '/book/{{title}}'` title wasn't replaced with title text but still on the form of **{{title}}**
