Artist Data Incomplete

One of my top listened to artists (Beach House) is missing several thousand minutes of my listening time. The number of streams for each album/song seems to be accurate, and each album correctly links back to the right artist, yet the majority of that data is not reflected on the artist's page itself. For example, when I look at the data for their album “Once Twice Melody", it has roughly 4,000 minutes of streaming logged, which is the correct amount of time. However, when I look at my streaming time for the band itself, it is only at 2,500 minutes, which is obviously not possible. I would expect this band to be in my top 3 most streamed, but they are significantly lower because of this bug.
