i guess the question is "why ctrl+i ?"

Franck ? oh 10pm it's to late for you. good night, buddy ;)

Given I choose 'template1' from the templates below <= In Given you list the system before your action, here you want to add a new project in list, so you want list the projects

| template1 |
| template2 |
| template3 |

And the folder project contains:

| Project 1 |
| Project 2 |

When I add a name 'My Project' and add the start date <= i create a project <...> using a template <...> with a due date <...>"
Then I will have a new project 'My Project' with the default tasks <= "then the lists is :" <list of projects | due date>
Folder Project now contains:

| Project 1 |
| Project 2 |
| My Project |

here some comments about the scenario :
