[Solved] Blog layout not corresponding

Something strange is happening. Here is what I have done:

1. I created a site template in a test domain
2. I then created a backup of the site with Akeeba Backup
3. I used the backup to create with Akeeba Kickstart a production site in a new domain and everything went well
4. I started to edit the production site, but realised that the Blog layout looks different on the two sites.

There are two elements in particular that have problems:

• the date
• the Readmore button

You can see the difference in images 1 (original) and 2 (copy).
I created the blog layout using Pagebuilder CK, building a module which I then inserted into an article.
The two modules are identical.
The previews shown in the modules are identical.
But the module of the production site seems not to accept the settings in the frontend.
Site page with the template: [url] www.testsrp.it/index.php/blog [/url]
Page of the production site: [url] www.studioilloto.it/istituzionali/blog [/url]
I cannot imagine the reason for this discrepancy.
Can anyone help me?

Well, everything works well now...
I only modified the form a little and then deleted the browser memory.
With the cache cleared, the page appears correctly
