zenworks agent not picking up new workstation name

[dspender]

Built 20 new computers and need to image.

Old way with zen 7:

-Set Workstation name with zisedit.
-Image workstation and reboot
-zen agent does its thing and renames workstation from zis data
-new workstation object appears based on workstation name

Zen10:

Same steps except although workstation name is changed, the agent says the device name is the same as the pc that the image was taken from.
So no new device appears in the list.

I did check the box Device Dynamic Rename under Configuration/Management Zone.

How else do we automate the renaming of the Device Name when we create a new image (or rename an old one, assumedly).

Thanks!
