What kind of job is this?
What version of blade?
It's an NSH job, client version 8.0
Can your users make a copy of the job and run that?
There is blcli for this, NSHScriptJob addNSHScriptParameterOptionByGroupAndName. It looks like you first run ‘clearNSHScriptJobParameterOptionsByGroupAndName’ first. Maybe the clear will reset to defaults
