Paragraph spacings in Zoho Notebook are double-spaced only. Is there a way to keep the original spacing format?

Sorry I don't know the proper terminologies but the best way I can put it is all single-spaced paragraphs that I copy to Zoho Notebook become double-spaced paragraphs. It's very inconvenient and counterproductive when copying and pasting things from and to. Is there a way to have different text modes?
