Not-centered the mobile version of the website

Hello everyone, I’m trying to make the mobile version of my website responsive. I don’t know why, but I can’t keep the page centered. I’ve attached two photos to illustrate what I’m talking about. This is the website in question: https://shockwave-platform.webflow.io/



This is the Webflow project: Webflow - Shockwave](Webflow - Shockwave)

and I don’t know why when I scroll until the membership section, it more or less fixes itself.

Please help, I’m going crazy.

Thank you in advance.
