Oracle Publisher row level triggers

We are using Oracle publisher to replicate data from oracle to SQL server,everything works well but i see the rowlevel triggers captures old data and new data also so i am seeing duplicates records in HREPL_POLL for two operations,any idea why its tracks old data?its slowing the process as we are having multiple records.As per the trigger logic whenever updates happens its stores old data and new data,can it update data basing on primary key?or its the expected behavior
