CREATE TABLE didn't replicated inside do-db database

[Database System]

Hi,

I found CREATE TABLE on master didn't replicated to slave. On slave server ini file, I
have replicate-do-db = db_name. When new table is created in this database, it didn't
replicated to slave. Updating on exist tables are replicated. 

On a different server, slave didn't setup replicate-do-db, the CREATE TABLE was replicated
to slave. The privilege on replication account is the same.

The version I use is V5.037.

Any ideas?

Thanks,
Lisa
