OGG BD Coordinated Replicat Does't Load Json Files To S3(from thread 2 and 3) When Downgraded to 1 thread from 3 threads:

ogghubxxx-->(HUBDB1) /ggdata/dbxx/dirout/rdbxx> ls -l
-rw-r----- 1 oracle dba 34452 Jun 15 12:18 2020-06-15_16-13-57.505-RDBXX002.json
-rw-r----- 1 oracle dba 30621 Jun 15 12:18 2020-06-15_16-13-57.505-RDBXX003.json

Golden gate for big data with coordinated replicat process.
The target is AWS S3 , so we use golden gate for big data file handler with s3 event handler.  
The file format is JSON.

We use either -
MAP *.*, TARGET *.*, threadrange(1-2);
OR
MAP *.*, TARGET *.*, threadrange(1-4);

When we use 3 threads and then downgrade to 1 threads ( Stopping replicat process , changing .prm file and starting
replicat process ) , the JSON files generated by thread 2,3 and are still left in the ogghub server and not uploaded to AWS S3.
