Microsoft: Official Support Thread

I just bough Microsoft Office 2021 Home edition. After the payment I clicked on the Redeem Now button. It forwarded me to my account, Automatically checked the version, my code and finally approved the purchase. I installed it without a problem. What perplexed me is that when I checked my order history I saw two items. They are both Microsoft Office 2021 Home, bought on the same day. One of them seems to be redeemed, and the amount paid is $0. The second one is my order and the info shows the right amount. Also next to the paid item the install button can be seen (redeem item seems to be installed o no install button). Did I get two versions, one for free, one for payment? What happens if I return the paid one and keep the redeemed one? Is this a bug or was I eligible for a free copy?
