No problem. I glad you have the card working.
Have a good Thursday. 
As a supplement reference, I found some good detail in this PDF from “Server the Home” forum site. There was a link to pdf called “Setting up bifurcation.pdf”.
As the document was 1 page, I screenshot the document as a PNG. While this talked about Dual M.2 Carrier Card, the logic is valid with 4 slot Carrier Card.
