Grain Effect On Site

My Site is having some issues! I have been working on it for a few weeks and recently I have noticed that there is grain on the site when I go to publish it. I see it in the HTML code when I go to export the code however I can not seem to find how to change it in the editor.

[Webflow - OPTIX]

If you could tell me how to fix this issue that would be amazing
