mismatch XBEE-WIFI S6B HV ( Hardware Version )

I tested the XBEE-WIFI S6B with XCTU then I found that it shows different HV value from datasheet.

XCTU shows HV 2730
datasheet says XBee Wifi Modules return 0x1Fxx for HV command.

Which one do I use it?

PS : HS ,too.

This HV value is important to me because I use a flatform with XBEE modue and Xbee Wifi in same mounting connector.

So I need to find out which module is installed on the PCB board.

Both the S6 and the S6B manuals say the same thing. I am seeing 2730 on my XBee WIFI as well so I would guess it is an error in the manual.
