usageRights api returning multiple results for the same catalogID

So I'm using Graph SDK's usageRights endpoint to test license management for a transactable offer.

I'm curious to know how it is that I'm getting a result that looks like this. (actual property values masked)

For the same serviceIdentifier and catalogId I get two different results for the same user. The only difference being the actual usageRight id

{
    "@odata.context": "https://graph.microsoft.com/beta/$metadata#users('some-user-id')/usageRights",
    "@microsoft.graph.tips": "Use $select to choose only the properties your app needs, as this can lead to performance improvements. For example: GET users('<guid>')/usageRights?$select=catalogId,serviceIdentifier",
    "value": [
        {
            "id": "some-usage-right-id",
            "catalogId": "XXX:0001",
            "serviceIdentifier": "my.test-offer.plan1",
            "state": "inactive"
        },
        {
            "id": "some-other-usageright-id",
            "catalogId": "XXX:0001",
            "serviceIdentifier": "my.test-offer.plan1",
            "state": "active"
        }
    ]
}

When I unnasign this license and make the same call, I get the following result

{
    "@odata.context": "https://graph.microsoft.com/beta/$metadata#users('some-user-id')/usageRights",
    "@microsoft.graph.tips": "Use $select to choose only the properties your app needs, as this can lead to performance improvements. For example: GET users('<guid>')/usageRights?$select=catalogId,serviceIdentifier",
    "value": [
        {
            "id": "some-usage-right-id",
            "catalogId": "XXX:0001",
            "serviceIdentifier": "my.test-offer.plan1",
            "state": "inactive"
        }

    ]

}

This implies to me that for some reason, I have a "hanging" usageRight perhaps from some previous test.

My question is, how do I reliably determine which of these two usageRights is the correct one to use? Based on what I've written above it's clearly the second one but how do I determine this in code?
