Multiple instances of USB drive in network

When I look in network on Windows 7 I see the following (see screen shot). This seems to have occurred after firmware updates. Only one instance of NAS will open the others will give network error. Has anyone seen this and is there a solution.

More details - it is a 2 T cloud drive connected to network router with cable with a 1T my book attached to the USB port. The My book name is NAS which is how I used it when connected to a usb port directly to the computer. see screenshot below.
