When you add the "BluetoothLE1.Devicelist" to the List View (ListBLE.ElementsFromString) the device list already contains the BLE name.
If you are just seeing addresses and nothing else that means a name was never defined for the device.
Also, it sometimes helps to reduce the ListView text size to see all the text too. I believe the default text size is 22. In my opinion, setting the text size to 20 or even 18 allows you to view the details better.
Otherwise you will need to manipulate the text yourself to filter out the MAC addresses etc.
