Elementor css not working properly

Hello everyone, on the back-end with Elementor, everything is working fine. However, on the front-end, the CSS is not functioning properly. On the page, you can see three boxes, and when you scroll down a bit, on the back-end, when I hover with my mouse, the text and button appear. On the front-end, only one box is working correctly, while the other two boxes already display the text and button without hovering the mouse.

The page I need help with: [log in to see the link]
