Can't create UVs for my Alembic Fur groom

Hey everyone, I’m having trouble with making UVs on my Alembic fur groom for Unreal engine. I’ve been following their guide and documentations on the unreal website: XGen Guidelines for Hair Creation | Unreal Engine Documentation

And when It comes to the Applying Textures to Hair UVs part, specifically at the script part, the script keeps giving me this error: No nurbs-curves found in group, even tho I clearly have curves in that group. I’m at a loss here, I’m wondering if I did something wrong, or something: Imgur: The magic of the Internet
