Nighthawk 8000 can't change device name in Advanced > LAN Setup

[PhilFromCA]

I'm trying to change the device name on two printers from their HP device names to names like "Laser" and "Inkjet."  However, when I select a device from the list and click on the EDIT button, and then change the device name, the change doesn't take effect.  I have clicked on the REFRESH button after doing the edit, which does show the change.

What can I do?

What Firmware version is currently loaded?

What browser are you using? Try a different browser?

Is there any spaces or special characters in the name? 

Did you select the Apply button after making the edit change?

I'm using the latest available firmware, V1.0.4.84_10.1.84   (This is a copy-and-paste from the browser page.)  I should mention that I do admin work on the browser on an as-needed basis.  Which means in this case, I may not have done any admin work since I upgraded to this firmware.

My system is Win 10 Pro 64, updated to 2021H2 plus most recent MS patches.  My browser is Firefox 64 104.0.2 (64-bit) (copy and paste from Firefox help page.)

I did click on the APPLY button after making the change. I just repeated my earlier steps.  Here is a screenshot of the main LAN setup page after applying the change.

Is it only this one device that you can't change the name?
