So After a few test...the new page ui does not work with Songs that are imported via csv. Whats kind of logical because there  is still just one pdf fille as starting point. 
But anyway msp allows you to do this, so tried it, and If you  combine two Songs (insert from library from the three dots at the page view) from this file Things are getting messy. 
I did not try to combine one song from an csv import and one normal import, but maybe Mike could test it? Or tell what will happen then? 
Maybe this related that i use my own folder System, but you cant tell at first if the song you are working on was an csv import.
I think before editing you should export all the songs as separate files.
