Radheshyam,
It is not clear how you determined "...But actually I am getting entries of the count 388462....".
No matter, this is a simple logical error. You have overlooked something in your selections of data.
Download the first list (what you think should be updated)
Download the second list (what you think is actually being updated)
Compare the two.
Examine the discrepancies.
Best Regards,
