Thanks for reaching out with your concern about BoldGrid Post and Page Builder for WordPress. The section slider and content slider are premium block level components. I checked on your license keys and it does look like yours are active so you just have to make sure you have the Post and Page Builder Premium plugin installed and activated on your site.
You can download the premium Post and Page Builder plugin from your BoldGrid Central account.
I hope this helps! Please reach back out if you have any other questions for us.
