Creating a Playlist in Apple Music

Besides listening to popular music on Apple Music, I create a playlist in my account each week because I am a Cantor at my Church. I use this Playlist to rehearse the Hymns for a few days before the Church Service. My Question: Sometimes, after I create a Playlist and corresponding description, Apple Music changes MY Playlist Title and Description to the first Song / Recording in the List. Why is this Happening? It does not occur every time, but when it does, I have to search for the Playlist, locate it, change the Playlist Name and Description again. Sometimes this happen multiple times in one week with one play list! Frustrating! Thank you for and help you can Provide ----Rick
