Unable to delete songs from my "songs" tab

[chaiteo]

I recently added 3 songs from my local file to my spotify songs list. I've then wanted to delete them as they're not able to be downloaded to my phone. But no matter what I do, those songs can't be deleted and the greyed songs really irritates me on my phone. 

I've tried removing them from my phone, removing all local files, deleting the playlist it was in, and pressing the "x" from my laptop but nothing is working. 

Help would be much appreciated
