Symptoms

Approvals is being set to No Longer Required for a record

Cause

The 'mark closed' business rule is marking the record to inactive (active=false)

It is calling 'runMarkClosed' from the 'TaskStateUtil' script include.

The script include is checking below inactive states

SYSTEM_INACTIVE_STATES : [3, 4, 7], // task default inactive/close states

When the record is inactive, the approvals are set to 'No Longer Required'

Set the state to other values not in SYSTEM_INACTIVE_STATES.
