Hi, i need your help 
why when create a new project in Jira Cloud (software template kanban, scrum o bug tracking) create a new Schemas (Permissions, Workflows, Scree, Issue type)?
But in some cases if I use the default scheme (Default scheme permissions)

Is a Cloud Free versión.
https://support.atlassian.com/jira-software-cloud/docs/what-are-the-project-templates/
In this documentation dosn´t explain what happen with create a new project? (copy or create new Scheme?
In Documentation for Managing Jira Projects for cloud certification dosn´t explain .
where can i find this documentation?
Thanks
