Issues on pages presentation linked to plug-in update

I can’t edit my first post, but maybe it wasn’t totally clear. I Meant:

Since I have updated Events Manager to version 6, my site is in trouble with appearance. If I disable Event Manager plug-in, appearance is fine.

I have asked for help on Events Manager Pro Support Forum, but I (still) don’t have a solution yet and maybe you can have an idea to help me.

I have look in the DOM and the div#secondary is out of the section#container where it should be (as you can see on the screenshot here : https://nuage03.apps.education.fr/index.php/s/RAMFwYmpXygckAP).

Now, I have added a JavaScript code to force the div#secondary to get in the section#container:
setTimeout(() => {
let leParent = document.getElementById(‘container’);
let laDiv = document.getElementById(‘secondary’);
leParent.append(laDiv);
}, 100)

It does the job, but it is not quite satisfactory.
