The phrase that you bolded from my post does not refer to the icons that may appear in the Statements & Activity area. I am referring to the Card Bonus Detail list that is not visible until a month after the statement is generated.
American Express seems to be working to make the Statements & Activity icons more reliable, but the lists that are here are the final word on what you really received:
membershiprewards.com > Points Summary > Activity Detail > Click [+] > See Card Bonus Detail.
