i don't know, i did the same thing for other custom views/playlist and it always works (even if i don't understand i always have to set the view for a playlist because it resets every time i change something)
What i do is
1) Set the view i want (let's say artists)
2) open panel settings
3) change the settings i want (save)
4) save custom view settngs into the file
When i go back to the other playlist i still see album covers, the custum view selected is correct, but the tracks are on the right
Maybe it can be caused indirectly by a third setting?
I save this

for "best of" custom view
but then ....

As you can see, other settings are differnt but track position is changed in both views if i change in 1 of them
