Q: Apple Music Playlist not showing

Hello, i want to ask about apple music playlist, here is the detail:

iTunes 12.4.3.1 Mac OS X 10.11.6. (ps: this also occurred on windows iTunes)

The first i started iTunes and apple music and i opened a group playlist, for example: "Apple Music K-Pop", it will show more playlist when at the bottom of page,

but when i choose a playlist and going back to a page before, it won't show more playlist anymore

What i want to ask is: It is a glitch from apple music or from iTunes? i really love apple music than other competitor's since it's integration with iTunes and iOs, and i have planned to subscribe after 3-months trial, but i wanna maximum experience of it before i can choose to subscribe or end the trial.

Here i post the glitch that i feel now, i hope there is a solution, thank you
