I'm not sure if I'll be able to help because all of my 2012 Weeks have been booked as weeks, and the reservation windows haven't opened yet for my 2013 Weeks. But I'll go through a few things just in case it jogs something for you ...
If I click "Check Availability" then a "My Marriott Vacation Club Portfolio" screen comes up with DC Points info on the top and MVC Weeks info below. Like I said, without pending Points from converting enrolled Weeks I don't know if what I'm seeing is different from what you see, but at the bottom of the DC Points info there is a button, "Transaction History." If I click that I can see two lists, "Reservations Transactions" and "Points Adjustments Transactions" from the inception of the DC. This page shows which 2011 Weeks I converted to DC Points and how I used those Points. If it is supposed to show current/pending Points transactions, then you should be able to use those lists to determine how many DC Points you have remaining un-reserved. Does it work?
(Going back to that Portfolio page and looking at the Weeks info, I am glad to see that the DC Points conversion allotments are there through 2014, and it indicates that there will be no change in the allotments from the 2010 DC introduction through the 2014 Use Year. This isn't related to your question but it's the first time I noticed it out as far as 2014, so thought I would mention it.)
