My Question or Issue

 Yesterday I decided to make a new spotify account. On my old account, my "Favorite Songs" playlist said exactly how many songs I'd liked and contained every single favorited song. For some reason the "Favorites" playlist on my new account looks completely different and doesn't contain a lot of the songs that I know I favorited. I also unfavorited a song on the playlist but it's still showing up. I've attached an image of each playlist so you can see the difference (the new playlist is titled "Favorites", the old one is titled "Favorite Songs")
