Workflow Approval rule is failing when we delete Person Address

Summary: For Person Address, we have created 2 rules ie. when we change/Add address within the same Country then it should be autoapproved. Other rule when they initiate transaction for a different country then it is autorejected. When we try to delete we are getting error. We added null conditions also. but still we are getting error. Supervisor hirearchy is also there. Please find attached error

Same country rule

((Proposed Person Address != null) AND (Proposed Person Address.result.country != null) AND (Current Person LegislativeInfo.result.LegislationCode == Proposed Person Address.result.country) AND (transactionApprovalRequest.ViewInstanceName == "PersonAddress"))
