Problem With New Music in iTunes Match (Unknown Album)

Added New Music Last Week and now i got more albums on my iPhone than on my Mac. iPhone creates a "Unknown Album" for every Artist from the new Stuff I added. No Problems with my old Tracks. What can I Do? There is no Album-Title for these Tracks.... 😟 And Somehow I have one Album with 2048 Tracks in it. But I really don't have this Album on my Mac. Seems like there are lots of Album and Tracks thrown together..

Please Help! 🙂
