Same iPad is displayed twice

Have used this app to transfer photos between iPhone, iPad, Windows 10 PC without any problems. But recently I have noticed problem when I transfer photos from my IPad Air 2 to Windows 10. When I click on Discover Devices on my PC it finds my IPad ..but then a second iPad is also discovered. This is the same iPad and seems to have the same photos... any ideas why this is happening? If I wait for both iPads to be found I can transfer photos without a problem from either one of the iPads that are displayed.
