CMS Tab - Finsweet Attribute

Hey everyone,
I’m building a cms tab within static tabs. The inner tabs are using the Finsweet attributes to show dynamic data. But i’m unbable to show the content, I have checked all the attributes and stuff but nothing.

Using the correct format only shows in tab-link buttons.
If I add attribute inside tab-content element, it removes from tab-link buttons.
Check Model 1 and Model 2 for refrences.
