Calculated metric not including certain company scores

Students from Wollongong are looking through company scores in the new dislosure metric Aileen created, and one of the students noticed their company is not showing up, though the research has been done: Salvatore Ferragamo SpA 

I checked for some other missing companies, and here are a few others I found: Nike Inc., Zalando SE (only for 2019), Ralph Lauren Corporation, Louis Vuitton Malletier SA (LVMH). I looked at the research metrics feeding in that might be causing problems (the "no" parts of the calculation), but I don't see a pattern.
