Categories – Excluding the particular category of visualization in specific areas

Here is my site: http://tophistorie.pl/

I have a category that is responsible for displaying the publications in the slider (the slider shows certain publications if it has a specific category assigned). The problem is that this category also appears on my home page and in individual publications. This is how it looks on my site:

Homepage – https://screenshots.firefox.com/5YuQDW4kFxEXuaQe/tophistorie.pl
Single publication – https://screenshots.firefox.com/OCI1uBe0ZKUf20Km/tophistorie.pl

I would like to completely hide only this particular category (Entertainment) so that it does not appear in the areas shown above. The bar before or after this category must also be deleted.

Does anyone have any idea how I can do it?
