The Auto-Discovery window shows all of the IP/MAC addresses that the local computer knows about and displays them in a list which lets you quickly add them to the current address book.
Interfaces
The Interfaces list contains all of the network interfaces that were found on the system that contains at least one valid IP/MAC entry.
Clicking on an interface will display all of the IP/MAC entries that were "seen" by that respective interface.
Devices
The Devices list contains all of the devices that were "seen" by the currently-selected Interface.
Placing a checkmark next to a device will add that device to the address book.

Interfaces have multiple entries that do not necessarily relate to an end-device and are typically unwanted within the devices list; enabling this option will hide those entries.
Auto-Discovery uses the Windows ARP cache to discover devices on the network. Please note that these are devices that the current machine has accessed recently - it isn't possible for WoLEX to actively scan the network for devices for various reasons.
If you're finding that there are less devices being listed within the Auto-Discovery list than expected, you can then try accessing the remote device(s) either by browing any of their shared folders or any other means that results in the current Windows machine WoLEX is running "talking" to those devices, and then re-opening the Auto-Discovery window.
It is important to note that a device seen on the network is only listed under the Network Interface that it was seen by; if Interface1 "saw" Device1, then Device1 will appear under the Interface1 entry - and no others.
In short: For the devices that aren't appearing in Auto-Discovery, access or connect to them using Windows and re-open the Auto-Discovery window. They should now be listed.
