Bulk import yields inconsistent results

[harpatel1]

When we do Bulk Import as CSV file, it looks like multiple attempts for a same bulk import file yields inconsistent results. This behavior is noticed in STAGING environment. It is most likely that this would happen for JSON import too since CSV import is effectively JSON import.

Scenario:
New bulk import request:
53 Concepts returned under source. There are total 53 concepts in bulk import file so this seems correct.

Second bulk import request for the same file unchanged:
78 concepts returned under source. This value should still 53, we need to figure out what is causing this behavior and fix it.
13 concepts returned under source.

The result from the second import can be greater or less than the actual value.
