Two almost identical artists merges to one

Issue description:

I have two artists

-Merle Haggard
-Merle Haggard and The Strangers

if i scan my music files from both of them only one artist have albums on artist page and it is Merle Haggard and The Strangers. If i check album from Merle Haggard artist name is Merle Haggard and The Strangers. Merle Haggard artist page is empty. Fixing tags doesnt work. Tags are from musicbrainz and files have musicbrainz ids.

From a quick extract the tags does not looks good.

Like for “Too Used to Being With You” you have

ALAR=[Bonnie Owens / Merle Haggard and The Strangers]
MALAR=[cecadf94-2da3-4d30-8e1e-11ff91aac3c4, deb2448c-6fdf-4d31-921e-757630515dbd, 54771e2f-5bb8-4feb-8a4c-7008708e01c1]

By default album artist will split on / so you have 2 album artists but 3 album artists mbIds, this does not match so it’s ignored.

The track artists seems ok.

TL;DR; you need to be consistent with all the tags for Symfonium to be able to match things.
