Answer 1

1. Does the CA that the request is sent to know how to work with SAN certificates?
2. To create a request, use other methods, for example: domain Certificate Web Enrollment (if it works), the "Certificates - Local Computer" console (certlm.msc), the certreq utility

Answer 2

Create an appropriate template. The existing templates are quite modest, it makes sense to clone them and refine them.
