Can't Batch Add Custom Genre

I’m trying to add “Pop-Folk” as a genre. I went through the process of Options>Tag Panel>&Genre>Manage. I see it in the Manage screen just fine. But I can’t seem to actually apply it to my files. When I select a file, the Genre dropdown only has <keep>, <blank>, and Other.

I can just type :Pop-Folk” into the Genre column individually. But that defeats the purpose of batch processing. What do I do?

Check the settings whether user-defined values are displayed at all.

From the documentation about Custom List Values:

You can also configure Custom List Values per field. It allows, e.g., for defining a list of composer names to ensure consistent naming. Or a list of country names or languages if you’re storing those. It’s still possible to only see the values of the selected files if you prefer that, but an empty field on the Tag Panel now always offers the custom values (if set) from the drop-down list.

The Genre field has a dedicated option to Show only user-defined genres. If enabled, the drop-down list of the Genre field on the Tag Panel only shows user-defined genres after a restart of Mp3tag.

Thanks. Good to know. Interestingly, on other playlists, the Genre dropdown had a standard list of genres which was quite long and already included Pop-Folk. So I just used that. I don’t understand why on that first playlist, I couldn’t see either thing (custom one I added or the standard list). But I guess it was a glitch with that one list of files. All others worked just fine. Thanks again.
