Unreadable character when setting Android hostname with StageNow


I'm trying to set the hostname of a MC3300 with StageNow like it is mentioned on Change the Network Device Name of Android device | Zebra

When I print the barcode and use StageNow on my device, the hostname is set but it has a unreadable character before the hostname. The unreadable character is showen in my Windows DHCP server and when I ping the device. I have used StageNow 3.0 and 2.1 with the same result. I also have tryed different versions of MX settings and this has changed the unreadable character in some way but there is still one character before the readable hostname. What am I doing wrong?

Thank you

With kind regards
