[NSFW] ICON problem

Hello.
I’ve reading all the posts that there are about the icon problem, and did almost everything to check it.
The problem with the site is that the icons are not shown on the pages where I’ve uploaded my personalized icons, but they appear on the rest of the sites.
If you check on the menu, the section hallsokontrol, fontawesome fonts dissapear, while they dont do in on other pages.
I’ve installed the fontawesome plug in, updated elementor, but nothing.
This allso happens in the elementor editing menu, where all the icons got changed, or dissapear. It’s funny cause arrows are replaced by my icomoon set.
Please, i need some hekp!
