If the Project Create View on the Project Object includes the Template checkbox field, this issue will occur. The Template (yes/no) value will be copied over from the template to the new project. Attributes configured on the Create page provide a method to ensure the default settings are saved when an instance record is created.
Release: All Supported
Component: Clarity Project Management
In order to prevent the new project from being created as a template, the Template checkbox needs to be removed from the Create View. It can remain on the Edit view, if already there.
