Dispersible Amount Vs. Award Amount?

So I'm looking at the school website thing for my aid. I qualified for the Pell Grant, Direct Subsidized Loan, and the Unsubsidized Loan this year. There are 2 columns. One is Dispersible Amount, one is the Award amount. Under the award amount, it says my award total for 2011-2012 is $16,050, which means that in addition to the Pell Grant, I got both loans. However, under Dispersible Amount, it says my total is $5,500, which that amount includes only the Pell Grant. My school does the thing where they disperse the loans each semester in different parts, and I understand that, this will be my fifth & sixth semester. Dispersible means "to distribute", right? So, did they award me $16,050 but decided to only give me the $5,500 for some reason? I'm going to be full time again this next year, and my GPA is 3.5, and I've gotten a subsidized loan every semester I've been in school so far, so it's not like I've done something wrong or I've went bad on the loans or anything. Is that just how they list it, am I still going to get all that money?
