MOLICHINO HAIR - STAR - [DEMO] (add me)

I'm quite confused about the permissions. The marketplace states that it is modify+copy, but the demo is not modify.

Now I do not know if this is because this is a demo and it wasn't spoosed to be modifyiable (in which case the owner should update the SLX permission details) , or if this is a genuine mistake and none of the full product items will be modifiable either.
For me that is important, as I would like to have the option to 'tint' certain shades of blonde or brown to achieve the color I want.
