Icons from a plugin don't work with GeneratePress

Hi :)

I'm using a plugin to show affiliate products on my website, but "icons" related to it are not working with GeneratePress.
On the link in private information, we should see 2 arrows to navigate in the carousel which present different products (at the beginning of the page)
I also put a screen with an exemple without the issue (we can see the icons)

On other websites without GeneratePress, the plugin works well and I can see the icons.

Do you have any idea about this issue ? Maybe a conflict with the CSS used by generatepress ?

thanks
