Weird Alphabetical Sorting Issue

[wrrryyyssoftly]

So I like to keep my song list organized alphabetically by artist.  Before adding songs from The 1975's album from 2016, I had no issues.  However, a very strange issue occurs when I add any more than 1 song from the album to my song list- despite being set to be sorted alphabetically, the songs will appear seperately on the song list instead of together, with other artists between them, and even causing other artists' songs to be separated from that artist's other songs, like with what happens to 009 Sound System in the pictures attached.  I don't get what happens and it bothers me deeply.  It only affects artists whose names begin with a number, and it even has different effects depending which songs from the album I have saved.
