Hi jsm
The issue here is about styles. It seems that the styles in the various
documents have been formatted differently. If a style is bold in one
document, but not bold in another, then copying from one to the other
"reverses" the bold (because the text takes on the formatting of the
recipient document).
More details and information about what to do is at
Why does text change format when I copy it from one document to another?

Hope this helps.
