Yeah you are missing the hardware details for the device. It was a known bug in the swap apps a while back but it should be fixed at this point. So maybe you did a swap on it a while ago.
I checked and my switch and dimmer drivers do not have the code to get that data patched in yet. You can use this driver: [RELEASE] Z-Wave Universal Device Scanner and run the "Get Info" command. Do not need to run anything else. Refresh the page and then check the data section again, should have mfg, deviceId and deviceType. Then switch back to the dimmer driver and run configure again. That should sort it out.
