Multisite problem

Hello
I use the pro version to manage multisite content but there is a problem.

Little explanation : I have 2 “sub-sites” that contain news articles of their own and a main site that groups them all.
I use the Elementor Pro page builder and the shortcode of your plugin to put my latests posts in the webpage.

The display of posts on the 2 “sub-sites” is displayed correctly (with an excerpt for each post written by me) but the main site does not display the posts in the same way at all.
Indeed, it puts all the content of the posts in preview, while I also selected “text content : excerpt” in the advanced parameters.
Why does not it work properly?

I bought this plugin for the management of multisite, so I am a bit disappointed.

Thanks to answering me quickly.
