Is it just me, hoặc did Anna and Elsa seem a bit OOC in Nữ hoàng băng giá Fever?

I know both changed a bit and learned something at the end of Frozen, but both personalities just seemed...off. It's kind of like they switched personalities. Elsa seemed a bit jumpy and Anna seemed overly calm (for Anna, at least). If anything Anna seemed like Elsa and Elsa seemed like Anna.
