cannot update using generated log

Hi,

I generated a change log file using the generateChageLog option. I then added one changeSet to the end of the file with a different author but the same running id. I then run the command
“java -jar liquibase.jar --changeLogFile generatedChangeLog.xml update” with the intention to run only the newly added changeset but it now tries to execute all changesets in this file.
Can someone help me on this?

Thanks,
Praddy

forgot to mention the version - it’s 2.0.3

Thanks,
Praddy
