Edit title of an assignment with pencil icon work, but only on course frontpage

On course frontpage, when you edit the title of an assignment with pencil icon it work well, but when you go to the Grades section the title of the same assignment didn´t change.

To make it work, i have to update the assignment in the traditional way. Is important to say that the "assignment name" when you update the assignment has the new title, so its seems need to be "update" manually to take effect in other places like grades.
