Restrict Sprint Management permission at the project Level

[govinda agarwal]

I have set of administrator role people who can manage Sprints in my project e.g. create, close, reopen etc. 

I created a project role called "Sprint Manager" with desired users who needs to have access to manage sprint and then added it to my project scheme to grant access to this project role e.g. Sprint Manager. 

However they are still able to manage Sprint. Not sure what I am missing here. I thought the project level permission could override the global level access like administrator which seems to have access to manage sprint by default.

Hello,

Permission do not override each other, they add permissions.

So does that mean the global administrator permission have manage sprint permission for all projects and it cannot be restricted at the project level?
