Problem with Litespeed Cache

Hey,
The last month I move from a Newspaper theme to generate press to use some features of the theme, but I have a problem.

In the old version of my site which I used a newspaper theme, I have a high score speed on the google speed tool and the site was very fast, after I replace the newspaper with generate press, the site speed dropped by 25% on desktop and 50% on mobile while I use the same caching Litespeed plugin and other plugins, even more after I install generate press I remove more of plugins. I try many different solutions until I get 99% for desktop and 95 for mobile on google speed but the issue the site shows the home page with only elements (take a look at the attached images) then it loads the homepage design.
