My Question or Issue

Hi there, I have difficulties to undersrand how to get offline music. When online, I have obviously access to my music inside my playlist ... but when offline I only have access to some songs.

What is the usage of the "download" button ? 

I can see for each song I have the possibility to "download" in front of each .. what does it make different with the download button ?

Many thanks !

I will try to explain more what I can not understand, including pictures ...

Here I am connected, all fine and you see the yellow arrows see screenshots :

I go offline, without touching the "available offline" setting, you can see all my songs are now available offline :

but If I now change the flag to "Download", still being Offline, you can see that only a few songs are available offline ?!? how is this possible ??

... and if I set the flag back to "download", still being offline, My songs are not coming back ...

So I do not understand the behavior ...

Can someone please support ?

Many thanks !!
