[Solved] PB CK modules and cookies

I suspect that PageBuilder CK modules do not handle cookies and cache memory well; they lead to puzzling results.
I usually create PageBuilder CK modules that I then insert into articles. That way I have the freedom to easily create portions of code that would require more work and insert them into all the articles I am interested in.
However, something is happening now that I do not understand.
See www.studioilloto.it .
I use PageBuilder CK modules to display the blog articles on two pages:
    - on the Home page I show the featured articles (at the moment only 1)
    - on the Blog page I show all the articles in the Blog category (currently only 2)
The correct appearance of the modules should be as in figures 2 and 4, but either I see the Home page as correct, or I see the Blog page as correct.
If cookies are enabled, the appearance of the forms is as in figures 1 and 3.
If the appearance of the Home is wrong, I delete the cookies: its appearance is as in figure 2 and is now correct.
If I now click on the Blog menu, the appearance of the forms is as in figure 3: it is wrong!
I delete the cookies again, and the appearance of the forms is as in figure 4: they are now right.
Now I click on the Home menu, and the appearance is again that of figure 1!
In short: either I see the Home correct, or I see the Blog page correct.
I use Firefox on Ubuntu Linux, but this malfunction also happens with Chrome and also on Android.

Note that I had used PageBuilder CK modules to build the Home Page sections, but the handling of the figures was chaotic: either two modules with identical images or modules without images.
In the end I did not use the PageBuilder CK modules and wrote the HTML code by hand. Now the sections work fine.
Can you verify the reason for this malfunction?

Hi
Please go in the component options >> use compile css >> set it on NO
then tell me if it works
CEd

Yes, Céd: now it works fine.
So has this option always to be set off (in any website)? Or you're going to make some changes in your code?

this option shall be turned off, I have tried to solve it but it seems buggy anyway
I have to remove it because the optimization shall be done with a specific extension

I agree.
Thank you!
