Multisite is not forcing SSL url slug on new sites.

Hi, i have problem. When a new user signs up with new site, the wordpress slug that you see when publishing a new page is still http:
Here is the image

I dont’t understand why are new users with sites not created with SSL?

This is my wp-config

define('WP_HOME','https://domain.com');
define('WP_SITEURL','https://domain.com');
define('FORCE_SSL_LOGIN', true);
define('FORCE_SSL_ADMIN', true);

And this is my .htaccess

RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]

# add a trailing slash to /wp-admin
RewriteRule ^([_0-9a-zA-Z-]+/)?wp-admin$ $1wp-admin/ [R=301,L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(wp-(content|admin|includes).*) $2 [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(.*\.php)$ $2 [L]
RewriteRule . index.php [L]

Other than that ssl is setup correctly and everything works but i had to manually change http to https for main website and figured that once wordpress knows root is https, it creates new sites also with https.

Can anyone help please?
