Few fixes

- Thumbnails for SR Nitta Minami "Silver Dolphin and the Hot Wind" do not display
- SR Kiryu Tsukasa "Freshly-Harvested Beach Girl" has no release date (should be August 11, 2018)
- Release date for SR Nagisa Aino "ドリームアドベント" is incorrect (should be May 12, 2019)
- No labels for upper menu icons starting with Notifications, at least on mobile

Thanks!
