Last.FM - track identification issues for specific artist

[Idyllwilde]

Hi I've been trying out some basic last.fm functions and everything is working great except for 1 artist called "a.s.o."

• One of their tracks can not be found even though it is on Spotify and it returns the following error message:
  "Spotify по типу track не нашел: a s o thinking"
• Another track of theirs is wrongly identified: "a.s.o. - Somebody" enters the playlist as "D.O. - Somebody"

Anyone have any ideas why this is happening and how this could possibly be debugged?

The function I'm using:
function lastfmTop12Months(){
let tracks = Lastfm.getTopTracks({
user: 'x',
period: '12month',
limit: 100
});
