Have a look at this thread to see how many different ways there are to get multiple values into one (type of) field:

> Hi Folks, Have recently switched my workflow over to MP3TAG and have recently completed curating my audio library. I'm in the process of revisiting the "Genre/Style" meta-tag in an effort to ensure that it is a simplified as possible and adheres (albeit somewhat) to standardization. I figure I'd post some links - most of you probably have already - that I found in case other newcomers to the community are looking for them.

You can check in MP3tag if you have real multi-value fields by opening the extended tags dialogue (Alt-T). For real multi-value fields you should see 2 entries with the same field name.

If you do not want it to be like that, you can merge these fields with an action:

> **[Merge Duplicate Fields – Mp3tag Documentation](https://docs.mp3tag.de/actions/merge-duplicate-fields/)**

> Documentation on the Merge Duplicate Fields action type that can be performed as Quick Action or as reusable workflow from Action Groups. Mp3tag is the universal Tag Editor.

Also, you can check the column definition for the field where you see `\\`: if there is something like `$metasep(genre,\\)` then you see the contents of all multi-value fields.
