Unreadable character when setting Android hostname with StageNow



I'm trying to set the hostname of some TC56 and TC57 with StageNow 3.2.

When I print the barcode and use StageNow on my device, the hostname is set but it has an unreadable character before the hostname. The unreadable character is shown in my Windows DHCP server and when I ping the device. I have tried 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
