Whow to use Album and Single nodes in music library properly?

I’ve scanned a folder containing music material in form of album_file+cue into the Music library, and noticed that the Singles node of the Music library contains three entries, and they are songs, not albums Kodi has recognized as music singles.

Am I right thinking that Singles node is a Kodi’s attempt to recognize if it deals with music album or music single and sort them accordingly?

If so then how could I tell Kodi the specific music albums are actually music singles?
