Adding new Debezium Connector to Apache Kafka restarts snapshot - apache-kafka

Question

I'm using debezium/Kafka(v1.0) that uses Apache Kafka 2.4.
In addition, I have deployed a debezium mysql connector that monitor some tables configured to take snapshot at beginning, at this point is all good.
After a time I have the need to start monitoring other tables, so I create another connector, this time without snapshot because is not needed.
This produces that the first connector start to take the snapshot again.
Is this an expected behavior?
How is the procedure to start monitoring new tables without the others connector take the snapshot again?
thanks in advance.
EDIT configs added:
First Connector
{
"name": "orion_connector_con_snapshot_prod_v1",
"connector.class": "io.debezium.connector.mysql.MySqlConnector",
"tasks.max": "1",
"key.converter": "org.apache.kafka.connect.json.JsonConverter",
"value.converter": "org.apache.kafka.connect.json.JsonConverter",
"database.hostname": "my_host",
"database.port": "3306",
"database.user": "my_db",
"database.password": "*********************",
"database.server.name": "orion_kafka",
"database.history.kafka.bootstrap.servers": "kafka:9092",
"database.history.kafka.topic": "history_orion",
"database.history.skip.unparseable.ddl": "true",
"database.history.store.only.monitored.tables.ddl": "true",
"table.whitelist": "my_db.my_table_1,my_db.my_table_2,my_db.my_table_3",
