nsrpolicy - did something change in ver 19.3?

Occasionally, a VM that was deleted from vCenter (but which wasn't removed from a Networker group) would result in a backup "failure".

 

I have previously used this command to eliminate this error (that's not really an error): 

nsrpolicy group update vmware -g -O

 

But, when I just ran this command, it comes back with this message:

195173:nsrpolicy: No items to add or delete.

The syntax of this command is:
nsrpolicy group update
--group_name -g
[--comment -c ]
[--server -s ]
[--debug -D ]
[--help -h]
Additional parameters to be specified for 'vmware' type are:
nsrpolicy group update vmware
[--vcenter_name, -V vCenter name]
[--add_vmware_clnt_list, -o ex. /MyFolder, /DC/host/vm]
[--del_vmware_clnt_list, -O ex. /MyFolder, /DC/host/vm]
[--backup_optimization, -z capacity | performance]
[--help -h]

(I'm pretty sure I had the group name and UUID correct when I ran the command)

 

Did something change in Networker 19.3?  Do I have the wrong command syntax?
