Plugin is not working with the text of my post

Hi guys thanks for the plugin it's pretty awesome but i am having some issues with my theme (Neville Theme) i don't know if my theme is the problem.
I hope the images let you see the issue. (The first image is how it looks on the theme demo soo how it should be shown,the second how its shown with the Advanced Gutenberg Plugin, and the third is how it's shown with the elementor plugin)
When I start adding text on my posts (paragraph) the text seems ok,but when i click on the previsualization it just doesn't look as it should look, in terms of the demo and the gutenberg advanced plugin. I really wanna use your plugin please help me with this issue.
Thank you so much!
