When you set autodetect\_column\_names true the very first event that the filter sees is parsed as column headers. Once that is done it is never re-done. If you have multiple files with different columns the only way to use autodetect\_column\_names is to pass them through different csv filters. See [this](https://discuss.elastic.co/t/logstash-cant-recognize-csv-columns/196396/2) thread.
