Issue is here https://github.com/netbox-community/netbox/blob/develop/netbox/netbox/choices.py#L87 as btn-outline-dark is not visible in dark-mode. However this would require a migration to change the values as the choice is stored in the DB, there are also a lot of references to btn-outline-dark in https://github.com/netbox-community/netbox/blob/develop/netbox/dcim/tables/template_code.py and https://github.com/netbox-community/netbox/blob/develop/netbox/templates/extras/inc/format_toggle.html which should probably be changes to btn-outline-secondary.
