Add a track to a playlist when you have multiple playlists

[laurajohnson]

I am having difficulties with the web player for spotify. I have a lot of playlists and am trying to reorganise some tracks. However, when I go to add the track to a playlist, only a number of them (maybe the most recently made) are available on the drop down list, and I cannot add the track to the one I want to as it is not listed. 

Any suggestions?

Thanks!
