Apex Superbadge Challenge 4 Error

Challenge Not yet complete... here's what's wrong: 
The 'MaintenanceRequest' trigger does not appear to be handling bulk operations correctly. For the positive use case of inserting and updating more than 200 records, it did not produce the expected outcome.

When I debug, I see this strange SOQL:

11:07:41.744 (4865812076)|SOQL_EXECUTE_BEGIN|[35]|Aggregations:0|SELECT COUNT() FROM Case WHERE subject LIKE '%AMC Spirit%'
11:07:41.744 (4868187164)|SOQL_EXECUTE_END|[35]|Rows:201

11:07:41.744 (4868273203)|EXCEPTION_THROWN|[35]|System.AssertException: Assertion Failed: Expected: 402, Actual: 201

11:07:41.744 (4868515907)|FATAL_ERROR|System.AssertException: Assertion Failed: Expected: 402, Actual: 201



I see many people passing this challenge. Kindly help!
