Hi Manuel.
The s2Member user export CSV formats those custom profile fields that way. Instead of a column for each existing custom field in s2Member, only those fields that actually have a value for the user will be exported.
So a user may have just one field, and another three fields. s2Member won’t put a field always in the same column, instead it exports them in name-value pairs.
The importation tool explains this with an example too. [hilite path]Dashboard -› s2Member® -› Import/Export -› User/Member Importation[/hilite]
I know it’s not a usual way to do it, so we’re changing this in the new s2Member we’re developing.
I hope that helps.
