No, the code doesn't remove it from the source code, it just hides the first two sections. If you want to remove it from the source code you should find the problem maker. 

It may be a theme or some builder plugin. 

The easiest way you can hide the first two sections using the CSS code: 

Dear Asti, will using your code in CSS remove wpDiscuz duplicates from source code?

section.fusion-tb-header > #wpd-post-rating, .fusion-page-title-bar > #wpd-post-rating {display: none !important;}

Many thanks, that works fine.

This issue comes from the structure of the content on your website. Actually, wpDiscuz displays the rating before or after (depends on the option you've chosen) the content of the page using the hook. In your case, the hook can be used several times on the same page, so it displays the rating section several times. 

The easiest way you can hide the first two sections using the CSS code: 

section.fusion-tb-header > #wpd-post-rating, .fusion-page-title-bar > #wpd-post-rating {display: none !important;}

You can see it on this page for example: https://customerdriveninnovation.digital/kollaboratives-arbeiten/

Please leave a screenshot of the section "Display Ratings" option and an example URL as well. 

I have a problem showing article ratings in my Avada theme. When I choose the option "show before content" or "after content" the article raing is shown three times :(

I think that's because I use the Layouts-Feature provided by avada and handles each section I add to a layout as "content". When I disable Layouts everything is fine. But I need the different layouts ;)

Is there any way to place the rating with a shortcode (or some php-code) manually?
