fleetctl. This does appear to be a bug of some kind, still confirming.
When creating a query pack config file, if ‘removed:false’ is not specified, the mode defaults to including removals. However, the UI displays the ‘Differential (Ignore Removals)’ option.
When ‘removed:true’ is used, the UI displays the correct selection - ‘Differential’
I am unsure what is expected default mode if the ‘removed:true/false’ line is not included.
