Evaluation: Unexpected error running Liquibase: There is already an object named 'X' in the database

Hi,
I’m evaluating liquibase using the docker container (and no pro license) on windows 10. Here is the process I am following based on the quickstart tutorial

created liquibase.docker-mssql.properties with these proterties/values:
url: jdbc:sqlserver://:1433;database=LBTEST
username:
password:
liquibase.hub.ApiKey:
liquibase.command.hubProjectId:

docker run --rm -v C:\software\liquibase:/liquibase/changelog liquibase/liquibase --defaultsFile=changelog/liquibase.docker-mssql.properties --changeLogFile=changelog/changelog.mssql.xml generateChangeLog

Reviewed changelog.mssql.xml and verified existing sql table, actor, in LBTEST is recorded

Add changeset to XML file creating a new table, actress

docker run --rm -v C:\software\liquibase:/liquibase/changelog liquibase/liquibase --defaultsFile=changelog/liquibase.docker-mssql.properties --changeLogFile=changelog/changelog.mssql.xml registerChangeLog

docker run --rm -v C:\software\liquibase:/liquibase/changelog liquibase/liquibase --defaultsFile=changelog/liquibase.docker-mssql.properties --changeLogFile=changelog/changelog.mssql.xml update

errors with:
Unexpected error running Liquibase: There is already an object named ‘actor’ in the database. [Failed SQL: (2714) CREATE TABLE actor (id int IDENTITY (1, 1) NOT NULL, firstname varchar(255), lastname varchar(255), twitter varchar(15), CONSTRAINT actor_pkey PRIMARY KEY (id))]

So clearly I have something incorrect? I have tried this using the an XML and SQL changelog and get the same error.
