Just got off the phone talking with a Marriott CSR. According to her, there was a little "glitch" with counting the 15 nights received from the new Premier Visa card. She said that the glitch somehow mulitplied that number by 5. This caused a number of people to be incorrectly upgraded to a higher status.
They have now fixed that problem and we should be showing our correct elite status now.
BTW, I did notice that they have corrected my additional of nights needed fields. They all seem to have the correct number of nights now.
