Can't Remove Z-Wave Device

I have Leviton DZPA1-2BW Z-Wave Appliance plug that became unresponsive on the network. I have tried excluding it multiple times and according to the color flashes it should be excluded. But this device still remains:

I can’t get it to add to the Z-Wave Network and I suspect this remanent is causing the problem. Is there another way to remove this or a file I can edit manually? Any suggestions would be helpful.

Yeah… same here…

I found this post but it’s not really user friendly
