I'm not sure what this means, and it's a minor thing, but I'm curious.
In the past with other hardware this has happened to me. This means your computer that has calibre running on it is connected to your network via a wire and wireless connection. Since your computer is connected to your network two ways, CC sees two calibre instances to choose from.
I had this happen with a video streaming app and connecting to the wireless vs the wired made a difference since the bandwidth required on the network for the video was so large. Most likely picking either won't make a difference to you since the data bandwidth required for calibre is relatively low.
You can fix this by disabling the wireless when you are connected to your wired network.
