My Question or Issue

 Spotify is set as default player on my GH Minis and when I ask it to play a song with specific album and artist name (in this case a rather specific German kid's audio book: e.g. "Bibi & Tina, Folge 11: Papis Pony") it just plays a random episode of said series of audiobooks (as if I had just asked it to play the artist only).

Google Home understands me correctly (as shown in the activity tab of the app) and if I enter the search query exactly as spoken, the Spotify app correctly finds and plays the right album.

What is wrong here? Is the Google Home not transferring the correct name to Spotify?
