Jfk customs question 4/7 cleared

I am trying to figure out why I have only been able to get 4 of 7 of my imports through customs last night. They are all from China and all the same item. I don't think that they all finished the customs process, I would hope that if the last 3 didn't get through last night they would have gotten through today. My next thought is that fedex didn't have space to pick everything up.
Hered the deal, I have 4 packages fedex attained and they should have had 7. The tracking is only updated past label created when fedex gets em after the initial stop at customs once they are in fact domestic.

And ideas, I am extremely thankfull that I have the 4 but it would be quite a game changer to have all 7 showing up and traceable. Thanks.
