Format Jumbled copying from Google Docs

Hi all

I am very excited to use this software and wanted to move a draft I was working on previously in google docs into Scrivener. I figured I would rebuild it by copy-pasting an introduction into it’s own section, but every time I try, it pastes everything on top of itself and I have no idea how to fix this, I would rather not rewrite anything so any help is appreciated.
