Nested songs displayed in Roon

I just added 6 songs by Linda Laurie and this is the result in Roon.
The first song doesn’t display the title, only the artist and no track number, it doesn’t play and 2 tracks below it are nested. Can anyone explain why this is and how I should rectify it? Also 1 track is listed as Track 30, even after I edited it and added the correct title Many thanks
