The latest release of Pathfinder Office 5.70 there is a slight change in some terminology within the differential correction wizard. In pre 5.70 your options for reference position are “Use reference position from base files” and “Use reference position from base provider” In 5.70 and going forward the options are “Use position from downloaded base files” and “Use position from base station list”.
“Use reference position from base files” and “Use position from downloaded base files” are the same option depending on your version.
“Use reference position from base provider” and “Use position from base station list” are the same option depending on your version.
