Did they age up Maddie?

I feel like in the first season is heavily implied that she's 14/freshman in High School. The way she dresses, how she deals with bullying, and even the way Justine talked to her in the beginning, as if she was a freshman, while Justine was senior. In addition, when Caspian first talked to her he even thought she was in Middle School. But then all a sudden, in season 2 her outfit changes drastically, the way she behaves also, implying she's 16. Also, there was no need for the "close up" scene on her driver's license other than to show the viewers that she's around 16. I know they probably fixed it because it would have been weird for 18 y.o Caspian to date a 14 y.o, so they made her older. However, it feels a little incoherent, to think she "aged 2 years" in the span of months. Maybe she just got more mature because of the trauma, but still...
