[Theme : Sahifa] : TieLab Meta Box in Custom Post Types

Hello

I’m using Sahifa (great theme !) and I have a question :

I have created a custom post type, which is working well, but I would like, in the backoffice, to have the Tie Options (Sidebar position, HeadCover etc) : this is available for posts and pages in the backoffice, but it does not appear in my custom posts.

Has anyone faced this problem ?

Cheers,
