I tried to remove one song but instead it removes N songs

[AlonsoCN]

Hi,

I'm getting strange behavior in desktop app (Windows 10), when I tried to remove just one song of my Starred list (right click -> "Remove From This Playlist") instead, Spotify removes N songs. I think that I created a bug when yesterday I added MANY songs to Starred list using multiselect functionality (I performed the next actions: right click -> Add to Playlist -> [PlaylistName]. What could be the problem? 

Thanks!
