Toddlers are very forgetful. They need to be reminded very frequently, u can try reminding her Everyday b4 she enters her ifc... ( though it is still not enough) Teach her there are other ways of being friendly.
They will grow out of it. Meanwhile be firm and keep reminding her. She may forget. They tend to forget easily. I always say toddlers have the memory of a goldfish
I would try to reach her another way to express herself with others. Such as shaking hands or maybe waving.
