Grails test-app is not executing statement

I am writing unit test case for service class. There is one method called getMemberStatusAndCurrentProducts. I have full filled both the conditions but still it is not executing inner statements of this condition.

Map getMemberStatusAndCurrentProducts(Member member) {
        def results = [:]

        results.memberId = member.id
        results.firstName = member.contactInfo.firstName
        results.lastName = member.contactInfo.lastName
        results.status = member.status
        results.email = member.contactInfo.email

        if (member.status == MemberStatusType.EXPIRED) {
            results.products = (member.activeEnrollments.originatingOffer*.products)?.flatten()?.unique()?.sort() { it.name }
            results.offerGroup = (member.activeEnrollments.originatingOffer*.offerGroup)?.flatten()?.unique()?.sort() { it?.name }
        } else {
            results.products = (member.activeEnrollments.originatingOffer*.products)?.flatten()?.unique()?.sort() { it.name }
            results.offerGroup = (member.activeEnrollments.originatingOffer*.offerGroup)?.flatten()?.unique()?.sort() { it?.name }
        }

        return results
    }

The if condition is shown covered but these statements are shown as uncovered

if (member.status == MemberStatusType.EXPIRED) {
            results.products = (member.activeEnrollments.originatingOffer*.products)?.flatten()?.unique()?.sort() { it.name }
            results.offerGroup = (member.activeEnrollments.originatingOffer*.offerGroup)?.flatten()?.unique()?.sort() { it?.name }
        } else {
            results.products = (member.activeEnrollments.originatingOffer*.products)?.flatten()?.unique()?.sort() { it.name }
            results.offerGroup = (member.activeEnrollments.originatingOffer*.offerGroup)?.flatten()?.unique()?.sort() { it?.name }
        }

Where activeEnrollments is method of Member domain, originatingOffer is an object of Offer domain. I am using test-app -coverage :unit <service_class> command to run unit test.

Can anyone help me in this issue.
