According to the Daz product page:

Quote - Built using the same Unimesh as Victoria 4, she can take advantage of many of the products that are also based on Victoria 4 like morphs, poses, and textures. The investment you've made in V4, Aiko 4, V4 Elite, and the Girl 4 pays big dividends with Stephanie 4 Elite.

Since it's built using the same unimesh as V4, that's probably why you get V4 when you try to use the CR2.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
