Mysql master slave replication

While performing mysql replication i am observing below issue:


Pre requistes : I have three mysql databases all located on different machines.
Lets suppose we have db1,db2,db3 and each of them have one table languages
db1 is the master of db2
db2 is the slave of db1 and master of db3
db3 is the slave of db2


Scenario 1
while inserting something in language table of db1 changes are reflected
to db2 in language tables but it doesnot propagate to db3 language
table.


Expectation - since db3 is the slave of db2 then above change should reflect in db3 as well but its not happening


Scenario 2
but while inserting something in language table of db2 changes are reflected in language table of db3 perfectly.


I dont know whats the gap in scenario 1


Please suggest if any configuration needs to be done
