Sync playlist created on Prime 4 Plus from internal SSD to Main Collection

Hi everybody, just trying to figure out how to sync playlist created on Prime 4 Plus from internal SSD to Main Collection, I can drag and drop it from Internal SSD collection (it’s forbidden). Also there is no new data to sync in sync manager. Also when I rename playlist on the device, software creates new playlist in the main collection but don’t change the name on existing one. And it disappears once I disconnect internal SSD. And one more thing, I can successfully drag and drop into another USB/SD/SSD collection Has anyone encountered this situation? Thanks
