Want to allow multiple sites with bp and mu

I want users to be able to setup multiple sites on my bp mu enabled site. The default mu setup will allow this, a user can add additional sites from the dashboard. Right now with bp enabled on my mu site a user can not add an additional site from their dashboard. There is a link that says create new site, but when clicked (https://mydomain.com/wp-signup.php) it redirects to the homepage. My bp pages are all setup correct and a new user has no problem registering or setting up the initial site. Pulling my hair out and I don’t have much left.
