Hilton HHonors - Prepaid booking shows Cancel from HH side, but active at hotel?

Booked the January Sale rate which was prepaid in full, somehow it showed canceled online and from the DD system also when I called to inquire about this.
DD called hotel (Hilton Sanya in China) for me. The hotel stated my reservation is active at the hotel system and advise DD to contact its IT for trouble shoot.

The DD agent noted this whole thing in my account at my request just in case something might change later.

Should I worry about this? All the way to China without a room is not fun. I will definitely bring my confirmation email with me. The actually stay will not come until June.

That just happened to me when I didn't receive my points for Conrad HK. One night of it was prepaid, and the points didn't process normally. The diamond desk showed it as canceled, but I did stay and they were able to pull the folio.

Something weird is going on.
