Copy Paste Artboard to a new file makes the artboards look differnt

I have been working in a file with multiple artboards. I have to combine all of the artboards from 3 differnt Adobe XD files into one, but for some reason when I paste the files into the new file - they look differnt. Not sure what is causing this issue. I tried on my PC and Mac. There aren't any interactions, hovers, components,  etc... Just a simple copy paste is not working. The first screenshot is what it looks like in one file, the second is what it looks like when I paste it into the new file. Please help.
