thanks for providing this info.
You're just one step ahaead of solving your problem.
I see in your screenshot that right now you cannot see all columns
Can you make your screen bigger (left top corner)?
If not: go to settings (click in right top corner) and disactivate activity of friends (you can put it on again later).
That way more of your playlist can be shown.
The column with 'recently added should show now.
Again good luck!
