The Album I added was The Blue Zone by Nic Potter the tracks are in flac format

if Fetch additional info is turned off no issues appear

The Artist exists in MusicBrainz but this specific album does not appear too
 

 I have just tried adding another album in this case The Smiths - Hatful of Hollow 

specifically because in this case both the artist and the album exist in MusicBrainz

and the there was no issue scraping the album

so issue seems to occur when either the artist or the album does not exist in musicbrainz
