UI flickering issues in Ember.js when loading breadcrumbs

I have bread crumbs component in my application to display the path of my current folder.I use a service called file which have a property called parent folders which holds the parent folders ids and name inside it.The problem is when I navigate across the folders for the first time the path is reconstructing from the first(flickering) whenever I move to another folder.From the next time onwards it is updating the current active folder properly without flickering/reconstructing.May I know how to fix this issue.
