Vtiger 7.1 Duplicate check conditions have or operator, should be and

Scenario and steps:

In Contacts module have set duplicate checking on last name and organization name.

A contact with last name Test already exists and does not belong to any Organization.

Trying to add another Contact with same last name but with value set for Organizatio Name as "Company 001".

Recommended solution:

Right now the duplicate check has "OR" condition so if any of the fields configured has a matching value in any other record it shows that duplicate record exists.

The operator should be changed to "AND".
