Why are some items in the Library grayed out? Can I still import them?

Anything you see in the Library that is gray and in italics simply means that you already have something of that type with that name in your account. Note that the contents of the items could be different, but they have the same name. You can still import anything even if it is in gray—you will just receive a message asking if it’s okay for Stock Rover to affix a number to the imported item’s name. Once it is in your account you can rename it by right-clicking that item and selecting ‘Rename.’
