Copying/Modifying A layout on another page Changes Home page layout

I am new to Webflow but not so much to web development.

Twice this has happened. There is a piece of code/an element that I want to use elsewhere on another page. I am able to copy it, I right click and hold to get to the ‘copy’ option.
I get it to where I want it, on a different page, edit. This has also happened where I didn’t copy the element, but I was working on another page that wasn’t my ‘Home’ page.

Once things look good and I go back and the layout is broken on my ‘Home’ page where I copied the element or just another section.

When I say broken, I mean the layout is running off of the screen or just looks different.
