When creating in the grid view, the blueprint association is set to blank, to allow the user to choose any available blueprint.
The 'New From Template' works differently. Any instance created from a template would assign either the standard or default blueprint.
Release : 16.1.1
This is by design.
Here are the scenarios when creating 'New From Template'
1. If the CIT template is not set with a blueprint, the CIT instance gets the Standard blueprint.
2. If the CIT template is set with the standard blueprint, the CIT instance gets the Standard blueprint.
3. If the CIT template is set with a default blueprint, the CIT instance gets Default blueprint.
