I assume you mean that you copied text and placed it into a hub. If so, is the original text in a Word document? If it is, there may be some code transferring over from it that's causing the problem. Word is famous for that.
If that's the case, just copy the text from the original document and paste it into a text document, which will strip out any code. Then, copy the text from the text document and paste it into your hub.
If it still isn't formatted properly, select or deselect "Word Wrap" under "Format" in the text document and try copying and pasting it again.
Hope that helps!
