My Question or Issue

"Lost in the Fire - Gesaffelstein & The Weeknd" (https://open.spotify.com/episode/51kb6FIF5rFvy2rGSqZuhX?context=spotify%3Auser%3Aspotify%3Aplaylist%...) to a playlist, but I only get the option to "Add to queue" or "Share". On any other song, I get all the options of the context menu. What gives? What is happening to Spotify?!
