Category page Problem

Hallo,

the plugin is perfect! I use it on some pages.
But it do now wokn on category page (description section). I get only code in browser like this https://prntscr.com/ch84u8
I tested widget in sidebar. It works. But not on page.

Interseting, that code WORKS in admin area of categories https://prntscr.com/ch85gv

Maybe i do anything wrong?

Thanks!
