Why tasks are not copied in the new workspace when user creates a workspace from a template?
Reason
The original Workspace type does not have the Tasks application enabled.
Resolution
Administrator must add the Tasks application in the workspace type.
Additional notes
The behavior is only dependent of the fact that Tasks application must be enabled in the workspace type.
If it is enabled for a given workspace, and this workspace has task(s) and then a template is done, the tasks won't be copied each time the template is used unless the workspace type is modified.
