Same set purchased two times

Hello, while browsing my premium purchased assets I noticed that the same set appears two times among my collection, as I've bought it two times. I checked my emails and found that I got two receipt for that set, but the Reference ID is the same. So I think I've been charged just one time, but it's strange that I got the content two times. Can this happen somehow? Thanks!
