This is happening with any device i connect, Tried with a Samsung On7 and a Xiaomi Mi6:

• Everytime that one device is connected, a entry is added
• If i remove the device, the entry stays and if i plug it again, another entry appears
• One entry opens the device, the others nothing does/happen
• Closing nautilus doesn't solve the problem
• Tried with another file manager, from elementary, the same thing happens, so i guess some of the usb libs are trying to be a rebel or something :P
