Playlist Edit Not Saved

Under “Edit Content” for a playlist.
“It is not saved like editing a list. When saved it is immediately reflected in the playlist.”

I’m sorry but I can’t parse this and I don’t know what it means. I do know that when I try to edit the playlist it doesn’t work. What does this message mean?

Edit content requires you to click “Complete” in the upper right corner to be reflected,
and the Edit list states that changes are reflected immediately, but I find it difficult to understand.
I’ll find the appropriate wording and correct it.

Rose_Love,

Thank you.
I started at MyPage->Playlist->Edit-> three dots-> edit name → complete then back out. The change is not retained.
When I clicked “Complete” the songs were not added to the Playlist in this circumstance. Normally, the songs are added when I make Playlist modification starting from other areas. Perhaps I’m doing something wrong I’ll check it again.

Hello,
I sometimes edit Playlists to rearrange the track order, and it works.
Once rearranged, I click the “Finish” button.
