I see the issue when I copy the component from site builder into figma using the figma plugin on v2.3. I don't see the issue though on 2.6 or 2.7 figma kits. So I am thinking its something to do with variables. I think your best course of action would be to duplicate the latest figma kit and include it into this project via figma libraries. Then you can just search within Figma for a layout, and paste it in - but you'll need to manually hook up the right variables - or you can customize the style guide of this latest figma kit to your old figma kit and all the components will come in styled as they should up to a certain point - hope this makes sense.
