3.What version of the list template? The version of the template should match the minimum version difference accepted by the site where you are attempting to use it. For example: you are saving a Sharepoint 2007 list and are trying to use it in a Sharepoint 2013 environment.
4.Some templates are hidden by design. Such as Project Tasks, Status List, Workflow History...
