The bug have been observed and reproduced with versions from 6.36 to 6.39.rc68.
In versions 6.36 to 6.36.3 devices displayed their name in name field normally (picture attached below). After update to 6.37.x to 6.39rx68, dude is unable to resolve device name for newly discovered devices, it only displays ip address. Everything is tested with default settings out of the box.
Please advise if there is an solution.
Cheers
