Problem with duplicating descriptions, texts, gifs for all products in the store

[Dominik6]

I have created a description for a given product, I have 4 of them on the page, the problem is that this description has moved to all products and when I try to hide it on other products, it hides on all. In general, I will not touch anything related to the products - photo, description, gif - everything is added to these 4 products. I've tried all options to deal with this but I can't find a solution. Has anyone ever had a problem like this?
