Clipper uploading everything twice

[Greenfly 0]

For the last month or somewhat longer, everything I upload using the Clipper shows up in my default notebook twice. Although I Web Clip many articles, they tend to be short, so I am not worried about using up my upload capacity. It is just annoying that I have to go through and regularly move half of my uploads, one at a time, to trash. I use two different computers, and this happens regardless of which computer I use. Does anyone have any idea how I can get the clipper to stop doing this?  Thanks.
