I just noticed that in Vistumbler v7 the "Set labels by mac" and "set manufacturer by mac" GUIs arn't working correctly. This seems to be a problem with the new listview sort function in AutoIt beta 3.2.9.8 - 3.2.9.9. I have posted on the autoit forum to see if this is a bug.

Edit: Its not an autoit bug. I will work on fixing this. In the meantime just don't sort buy header in those GUIs
