The shortcode doesn’t work

Hi, after having followed to the letter all the guides to make this plug-in work, I have a rather particular and disabling bug. I’ll explain.

After making the initial settings, if I create a new page, I add the short code and insert ‘ea_standard’ or ‘ea_bootstrap’ inside, if I see the preview of the page everything is displayed correctly. On the other hand, if I publish the page, you no longer see anything and read exactly what I wrote, so either ‘ea_standard’ or ‘ea_bootstrap’. This makes everything useless. How do I resolve? Thank you

Here is some information that may be useful to you:

Theme: Lodestar
Wordpress: 5.8.3

P.S. I used the ‘character instead of the [,] character to avoid problems.
