As the title already states there seems to be something "broken" in the CSV file. For example almost at the end of the CSV file (see screenshot). There are two empty names followed by the name "nas" which most likely is also wrong/not complete. Do you know what (full) names were listed there or shall these entries be deleted?

There are more of these entries, see lines 6325, 9458-9459, 9733, 9735, 13957, 34840.
