Hi and welcome here

Hmm, your stronghold hasn't definitely doors? That sounds like a bug to me. Even if you let the Telvanni woman decide about the soulstones by herself, she should have taken the right ones, that's why I'm thinking it is a bug. I've no idea if there is for such kind of bug an insert code and hope that somebody knows one. (Because a home without doors doesn't really sound like a home to me....)
