Month subscription never ends

Question

I've created new app add-on for purchase. It's a month subscription which pricing is free for testing purposes. After several cycles of purchasing add-on and then canceling it, the store api method Windows.Services.Store.StoreContext.GetAppLicenseAsync() returns a month subscription with expiration date of 9999-12-31 00:00:00. Here is the app license json:

{
  "productAddOns": [
    {
      "devOfferId": "",
      "inAppOfferToken": "subscription-month",
      "productId": "9N4VFZX8NXJT",
      "productType": "Durable",
      "skuId": "0020",
      "skuType": "Full",
      "expiration": "9999-12-31 00:00:00",
      "isActive": true
    }
  ],
  "productId": "9NH6D9HN5PLN",
  "skuId": "0010",
  "isActive": true,
  "isTrial": false,
  "isTrialOwnedByThisUser": false,
  "isDiscLicense": false,
  "expiration": "9999-12-31 00:00:00",
  "trialTimeRemaining": "10675199.02:48:05.477581"
}

I cannot cancel this one using Microsoft Store purchase API, because https://purchase.mp.microsoft.com/v8.0/b2b/recurrences/query does not return that subscription. In portal https://account.microsoft.com/services/ it shows that the subscription is canceled.
At this point I am clueless. Is there any way to work around this?
