Delay in showing results in Grade center

Hellow everybody,

I created storyline with a quiz and published to LMS SCORM 2004 to be used in Blackboard.

I chose to track using the ( When the user has viewed ).

However, i'm not able to see the quiz result in Grade Center. I see the in Progress icon instead. 

Below the student attempt page it reads:

This content item is still in progress. Once completed, the points awarded will become editable.
