Widget Logic not working with rokstories plugin, not sure why… theme? me?

I am helping a friend with his site… https://hateburn.com/

This where the theme is from… https://demo.rockettheme.com/wordpress/wp_zephyr/

He wants the ‘Showcase’ widget position at the top to only appear on his ‘Home’ page.

I have tried ‘Widget Logic’, is_home(), is_front_page(), ‘true’ inside the parentheses on both, home inside the parentheses on the front page, the number ‘1’, etc etc.

Is it the theme? Or am I not inputting the right information?

Thank you in advance for your time and help.
