InterProject Contracts Picking Cost for Billing even if the Contract is End dated .

Summary: We have multiple InterProject contracts which are associated to one Project. We tried to enter Contribution % as 0 or Null value for End dated contracts for which we are getting an error as shown below

So we gave 0.001 as contribution % and endated the contract. However when we are creating new cost and billing for a period which is after the Contract end date. It is picking up as ineligible tnx and showing as exceptions.

Since its a end dated contract it shouldnt have picked these for billing also Why is The System not allowing Contribution % as null value.
