Most Likely....The UAC settings were contrary to your 'default' when the ZCM Agent was installed.
When the ZCM agent is 1st installed, it backs up the current GPO settings to the "OriginalCache" folder.

When the GPOs are removed from the PC....These settings are then restored.

Most likely the "OriginalCache" has non-preferred values and you do not have a policy assigned that sets the preferred setting.

Try grabbing an "OriginalCache" folder from a machine w/o issues and copying to a problem machine and see if the issues clear up.

Note: I would do "Win7 for Win7" or "Win10 for Win10" on the copies....
