Update - I got 17,604 posted
After; I kid you not; 21 emails to Hilton. I finally got the points that did not post because the hotel identify themselves as Hilton brand hotels deposited into my account.
Most of my emails back and forth were just cut and paste responses from Hilton. Asking if AMEX had my correct HH number, another asking if my purchases were from the HHhonors mall ??!?!? Hu? The finger pointing back to AMEX was non-stop by Hilton.
After a long fight I got the points. BUT no one at Hilton is really looking at this issue. I do not think the get it. Still. or they do not care.
Keep an eye on your accounts if you have an HH credit card from AMEX or CITI as many hotels have issues in the way the show up on your credit card statement and you might not get the points you should.
