Problem css/lazyload with preload

Hello,
i think i am having problems with the preload of posts and categories.
For the .css and .js cache I use Jch opimize, with the “remove css unused”, the “lazy load” image and the css critical. (no page cache)
Is it possible that the preload of some posts/categories has some problems with .css and images with lazy load because it has not been “worked” by jch optimize? (css class not included in the page, and the images with lazy load displayed in gray).
Thanks for support.

PS. Jch optimize creates a different .css file for each post/categories.
