The notes on the import patrons page need to be updated (import_borrowers.pl) When importing and overlaying patron records, if the csv file has blank columns, the blank columns will overwrite existing information. For example, if a patron has a city listed in their record, and on the import, there is a blank column for city in the csv, the info will overwritten with blank. While not necessarily a bug, the following should be added to the Notes section displayed on the page, matching what is in the manual: When overlaying patron records, if your .csv includes blank columns, any existing values in patron records will be overwritten with blanks.
