Only eligible for half of my Fall financial aid

I qualified for the full $3698 per semester for fafsa. I'm currently enrolled in 13 credit hours (which to my knowledge is full time) but only $1849 disbursed. It says I'm "currently ineligible" for the other half. Is it because class hasn't started yet?

Planning on contacting office hours Monday evening, but wanted to see if anyone else has had this problem
