Webflow consultant & guidance

I am in the process of building a new website in Webflow using the Relume component library and other libraries that apply the copy and paste method of quick and convenient website building. When I copy and paste elements into webflow they appear fine. But when I publish to url the site is broken. Webflow gives me a message that "For pasting cross-site we had to drop some links/symbols". I think this might be the issue for the live site being broken. This issue and other upcoming queries regarding webflow is something that I need assistance with.
