Mobile/Tablet Editing

Hello everyone!

I hope you’re all staying safe and well during these uncertain times.

My business partner and I are new to Webflow and are working on building our company’s new site.
We are running into an issue when we attempt to make design edits on the mobile landscape as well as tablet view. We have edited our tablet view to show all content correctly, then, upon beginning to make some changes to the mobile landscape mode, we have noticed that some of the changes are carrying back over to the tablet and even desktop size. From what I have read and understand, when you make an edit on a smaller breakpoint (eg. mobile or tablet), the larger breakpoints are supposed to be unaffected. Is this correct? If so, why would edits on mobile affect the desktop or tablet size?

It should also be noted that not every change is carrying over, but there are definitely changes occurring, causing us to be forced to redo design work. We are very confused and would greatly appreciate any guidance at all to help us straighten out our site on mobile and tablet versions.

Here is my site Read-Only:

Thanks in advance!
