Closing, please follow the bug report guidelines. I have no idea what you are talking about here.
Can't provide anymore details then this: Editing values: It is simply pasting from clipboard into preferences column, doesn't remove the old value. For example I select/highlight ( when you swipe a mouse across the text while holding LMB ) variable entry value, and pres CTRL+V, and all it does it adds the clipboard element to already existing one instead of removing the old value an replacing with new one.
