[HSY] Teen Sim drops out of upon aging up instead of graduating

I am currently having this issue. It happened to one of the families I am playing with but did not happen to another family I played with. The family that it worked correctly with I was able to have the teen girl age up and was presented with the graduation notifications. With this separate family, when he blew out his candles and aged up, I got the dropout trait and notification that he dropped out of high school. Mods are installed in my game and were present with both families when being played.
