Asset Discovery Log Error

Hello

Running Asset Discovery and have enable debug logging. In the log file there is a message that I don’t understand. The message is error occurred: Error: class NotAMACAddress. I do see the xml file with results NMAP_ArchveFolder and looking at it I see MAC addresses for various discovered devices. The xml file does contain a number of discovered devices but nothing is appearing in the console as a unmanaged asset. Not sure what triggered this error message. Looking for some guidance.

It seems known bug & HCL registered it under below KB:
