According to bootstrap docs, we can add list groups into cards and use the 'list-group-flush' class to avoid double borders. https://getbootstrap.com/docs/4.1/components/card/#list-groups Bootstrap Studio correctly adds this class in the BSS UI, but the class is not applied to the preview or the published site. The way to get it to work is to manually add the class. Thanks, Stu
I wouldn't necessarily call this a bug as it's not broken per-say, it's just not implemented in the app yet really. It seems they haven't built in the recognition of what to do when a list is drag/drop 'ed into a card yet.

Thank you for reporting this! It is a bug indeed. I'm adding it to our to-do list.
