I just checked with a similar pack from Warlord that I have (which I have used in the past as it is from iClone 5) and something has changed, making the controllers visible.
The larger controllers for a group of pedestrians are dummies, but the smaller ones for the individual pedestrians are not. The only way to make them invisible is by setting the Opacity of their Diffuse channel (texture) to "0".
As this is rather involved, it would be best to contact the developer Warlord as this should be fixed. I don't have the particular pack, so explaining it for the pack I have would probably not help you.
