dragging files to itunes icon causes duplicates

been meaning to make a post about this for a while, but why is it that whenever i drag and drop files to the itunes dock icon i end up with 2 copies in my library? it's rather annoying to have to keep deleting the duplicates every time.
is this an issue or is there any way to fix it?
thanks!
