pt-archiver replicated inconsistent data

I have a master slave replication. Here i scheduled pt-archiver for table dltb which archives on condition insert_date<date_sub(now(),interval 35 days) to archive table dltb_archive on master .in master it is working fine when i checked that in slave data looks inconsistent . Still i can see older that 35 days in main table.Any one please let me know whats the issue here .

1 . Im using MIXED binlog format in both master and slave.

2 . pt-archiver --source h=localhost,u=root,p=,D=dltbdb,t=dltb --dest h=localhost,u=root,p=*,D=dltbdb,t=dltb_archiv e --where “insert_date < date_sub(now(),interval 35 day)” --bulk-insert --bulk-delete --limit=5000 --progress 50000

3 . Here is the delete query of pt-archiver which i found from slow log .
DELETE FROM dltbdb.dltb WHERE (((dl_id >= ‘0000AAAAAAAAA2DDASEDFFGGTHHHJ’))) AND (((dl_id <= ‘AAAAAAAAAAA5661BFSRDEYGYVSKUK’))) AND (insert_date < date_sub(now(),interval 35 day)) LIMIT 5000;
Here dl_id is varchar(64) PRIMARY KEY

Here is the pt-table-checksum report :
