Why are my purchased songs missing from iTunes?

Years ago, I purchased the “True Sadness” album by the Avett brothers and had no issues with it.

I wanted to listen to it again recently, but found that the first track “ain’t no man” was missing (first pic).

I went to my purchases to restore that song, but in my purchases menu, the first song is wrong (second pic).

I then realized that I’m actually missing more than one song. See full expected album track list in pic 3.

How can I get back those tracks without purchasing the album again?

additional clarification: I can see the album in my list of purchases, but when I go to the iTunes Store page for the album, it shows as though none of the songs have been purchased.
