This often happens if you add things to the cart when you are not logged in. Then when you log in to check out, the bug bites and the items don't show up. After logging in, add one more item to the cart. That will make the other 3 show up. Then delete the added 4th item. It is an annoying bug that has been around for a long long time.
I give up.
