Folder Portal details view bug?

Now that the beta has introduced network drive connection detection, the functionality of folder portals has greatly improved. I can take or leave hiding the details header but what really bugs me is that the actual columns that I choose to display don't stick from one session to another.

For example, the default columns for music files are displayed as "Name", "#", "Title", "Contributing artists", "Album". I just want to see "Name", "Size", "Length", "Date modified". So, I deselect and select the columns displayed as appropriate; my layout lasts only for that current session - it reverts to the default layout when I reboot. Is it possible to keep my layout - if not, I don't see the point in being able to change it in the first place - or am I missing something?

I should add that I have set the same details view, as above, in File Explorer in Windows 8 (just as when used in Explorer in Windows 7 previously).
