Car seat help.....

What am I doing wrong? We bought our LO a new Graco 4ever car seat. She rode in it for the first time today but I noticed when she’d fall asleep her head would fall forward. The car seat is level and on #2 recline rear facing. I can’t recline to the #1 because it makes it unlevel. I also tried with and without the head cushion, it didn’t make a difference.
