Cassandra Stress tool does not honor Consistency Level when using profiles

Question

I am trying to run a stress test using the cassandra-stress tool with profiles on a 6 node cluster with a replication factor=3.

./cassandra-stress user profile=/path/to/cassandra_stress.yaml duration=2h ops\(insert=20,select=10\) **cl=local_quorum** no-warmup -node nodeaddress -transport truststore=/path/to/tls/truststore.jks truststore-password=***** -rate threads=5 -log level=verbose file=/path/to/log -graph file=graph_.html title='Graph' & 2>1

The execution stops at some point with a ReadTimeout and the logs show the following:

com.datastax.driver.core.exceptions.WriteTimeoutException: Cassandra timeout during write query at consistency LOCAL_QUORUM (2 replica were required but only 1 acknowledged the write)

com.datastax.driver.core.exceptions.ReadTimeoutException: Cassandra timeout during read query at consistency ALL (3 replica were required but only 2 acknowledged the read)

I am not sure why it is taking cl=local_quorum for writes but not for reads. Any insights would be helpful.
