Issue with copy and pasted elements not reflecting properly in live website (from one project to another project) [Possible Bug]

Hey guys, I was copying and pasting elements from project A to project B and for some reason the preview looks different from the live website. Certain sections do not look the same (ex: Slider on preview looks fine but in the live version it’s all messed up)

Also, after copying and pasting the elements from one project to another, new buttons that I create seem to immediately change back to the default blue and shape even after I changed the color to yellow and edited the radius. In the preview version the buttons look fine but the moment I publish the website, the live version shows the default blue and rectangular button.

I’m a beginner at Webflow so would really appreciate it if someone could point me in the right direction. Here are the links to my website:
