I don't know if this is a bug or my own lack of skills, so I'll post without the BUG in the title for now.
I highlighted a sentence in one of my resources that happens to have a grey background shading.

When I right-click and put the selection into a clippings file, it picks up the background as though it were highlighting.

I would prefer to have only the text in the clippings file, but can't figure out how to make that happen.
What am I missing???
