Pasting Symbols to all artboards duplicates Symbol in the panel
Currently, if I copy and paste a symbol to all artboards, then it also copies them within the Symbols panel -- one for each artboard. I'm working in Adobe CC, latest update, on a Windows OS. This happens whether I use keyboard shortcuts or the Edit menu, and even if I only copy-and-paste one instance at a time. The only method that doesn't do this is holding Alt while click-and-dragging one at a time. Any idea how to make this stop?
