There is an small bug in alpha, when having the same CC session open, as you add more .las that have an illuminance__PCV SF, it when opening new files keeps stacking illuminance__PCV SF's, like it does not resset the text field.
EDIT: I just realized looking at the image that same occurs with regular SF's, like there are a *hitload of them.
