Entitlement of Service Work Orders against single Contract line

We are using JDE E1 9.2 and working on JDE Service module. We have a business scenario where a contract is covering breakdown and preventive both activities for business. We are maintaining two different WO types for Breakdown and corrective action due to business reasons. System is expected to perform Manual / Auto entitlement in service work order for breakdown and preventive action both with single line in contract.

When we configure system we need to link Contract line type with a specific Work Order type in SWM attribute of Line type in P1793 & When we try to entitle Break down service work order , entitlement is working fine as expected but when we create a service work order for Preventive activity from a Case or manually standalone , system is updating preventive work order type with the Breakdown on entitlement which is not correct.
