Tried to use one of 10 free assets but somehow bought a photo??

Yesterday I licensed two photos from adobe stock. I have the free trial which allows me to license 10 total photos for free. These two photos were my first two of the ten. However, I received a payment confirmation for the first photo. This does not make sense, because when obtaining the license, I did under the assumption that it would be one of the ten free assets. The second photo was charged 0 dollars, so I'm not sure what happened. This is very worrisome because the photo "purchased" was very expensive, over 200 dollars. What can I do to fix this??
