Welcome to the community @hclark9526!
I’m having trouble following the issue you’re experiencing and from what I can see everything to look fine on the larger breakpoints (main up to the 1920px). If I get some more specific information about what isn’t working as you’d expect I may be able to help out.
That said, you should always design your site on the main breakpoint and adjust only when the design breaks or could be adjusted to display better on either the smaller or larger breakpoints. Unlike traditional web design techniques, Webflow’s breakpoint cascade away from the base breakpoint (both up and down) so the process is a bit different than you may be used to.
I wrote a pretty lengthy post that goes over this process that you may want to check out below (which includes a link to the Webflow University tutorial on the subject as well):
One of the more common issues I see folks make is immediately creating the three new larger breakpoints even when they don’t intend to make many changes on larger screens. Depending on the design, a 1440px mockup could definitely be the same layout/styles as you’d use on your base breakpoint—meaning you wouldn’t need to even worry about managing that layout separate from the base breakpoint.
