A list is a special beast.. you can't add complex field types like columns/fieldsets etc inside a list. The JS is expecting list items to be directly under it.

This was an issue with the twig itself of the fieldset field. Apparently this is not such a commonly used field because it was still using old code prior to the revamp of the list field which allows any field to work within it.
Fieldset was never updated to work with that. Took me quite a long time to figure this out but should be good to go now!
