Duplicated content when using other plugins

Greetings to all.
I’m using “PageLayer” as well as the theme “PopularFX” to build my website. Currently, I want to add a lot of functionality to it to turn it into an e-learning platform using Tutor LMS, upgrading it from being a simple static website. The issue is that after installing the plugin and adding the pages, some of them have content that is duplicated three times, like this one: https://takweenpro.ma/tableau-de-bord/
Additionally, I attempted to create a video in the hero section rather than an image, but the theme and plugin don’t support that, and when I installed Elementor and did it in a separate page, the content was once more duplicated three times!
Do you know how to resolve this? Greetings and many thanks.`
