Create Trigger being generated in schema.sql for DB2 for z/OS upgrade

We are running the synchronize step prior to creating the staging schema. We are still generating a number of create trigger sql in the schema.sql inspite of having applied this to the database.

e.g. DROP TRIGGER SIEBEL.PTH0364

  /
  CREATE TRIGGER SIEBEL.PTH0364 NO CASCADE BEFORE INSERT ON
  SIEBELDA.S_ACCNT_POSTN REFERENCING NEW AS N FOR EACH ROW MODE
  DB2SQL WHEN (N.OU_EXT_ID IS NOT NULL) BEGIN ATOMIC SET
  N.PARTITION_COLUMN = RIGHT(N.OU_EXT_ID, 2); END

The bookshelf states no sql should be generated, i.e. physical and logical schema should be the same.
