Bug in New Project Creation for project Manager account

i am internal user(project manager) of account manager's account inside our organization. when i am creating new project it will automatically add account manager into that project. but in this case there should be invitation for users in new project. why should any user get involve without invitation.

for more practical example :-
consider ABC is account manager and XYZ is project manager which is internal user of ABC.
Now for first project created by ABC and add XYZ into that project -correct
But when XYZ create new project it was automatically add ABC into that project -Bug

Hope this will helpful for you.


Thanks,
Dharmesh
