Сharacters separate artists "\\" - How can I replace them?

[Zirrex]

Hello.

The following characters have started appearing in the artist name: “\\”
These characters separate artists.
I tried to remove them. I did Action - Replace, _ALL, \\, Replace with: ,
but nothing happened.

Other characters can be replaced. The problem is only with these.
Please help me solve this problem.
The link is to a flac file where this problem occurs -

Check the extended tags dialogue - that should show that you have 2 (or more) fields of the type ARTIST.

You can merge these fields with an action of the type "Merge duplicate fields"

Use a different separator (e.g. ;) than \\
