Why the album I bought doesn't appear in Purchased Tap?

I bought "Sounds Good Feels Good" by 5 Seconds Of Summer and "What Do You Mean - Single" by Justin Bieber, a few months ago.

when i go into Purchased tap in iTunes, I see only the album by Justin Bieber. I don't see for 5SOS. But when I goes into the album in iTunes, it says Purchased.

Explain something I don't understand. Is something wrong?
