Now that this has been merged into the existing thread, the whole thing is becoming more clear. Posts 201 and beyond are quite telling as to why this is an issue.

Also seems you knew this might be an issue:

Did you receive 10 nights for your first meeting at some point before these last 2? I seems you know the problem is receiving the nights’ credit for subsequent meetings. You tried to squeeze in a couple more cheapo meetings before August 18 just to try and get the 10 nights per and it has come back to bite you.

Yet according to this

“
It’s pretty obvious that for the new program, only the FIRST Qualifying Event of the year will earn 10 EQN now. After that, events only earn EQN based on the number of room nights consumed. It’s really that simple.”
And

“
As I posted way in the predecessor thread, the fine print said that you'll get rewarded according to what the program is at the time your event posts.”
So that seems to be where your problem lies. It seems you may have gambled and lost. Or you can fight this to the death and get your 20 nights and bogus status for this year but, as others have said, is this really the fight you want to take to Marriott? Someone who booked several cheap, questionable ‘meetings’ just under the wire just to get status and is not really profitable to them as a frequent paying guest? Up to you but I wouldn’t want to shine that spotlight on myself.
