How do I get rid of a Contacts group called "card" when it isn't in my Mac contacts?

On my iPhone and iPad, I have a group called "card" that appears to be a group that lists all my contacts, but maybe not, I haven't checked them all. This Contacts group is not in my MacBook's Contacts application, so I cannot delete it from there.

Because this group exists on my devices, it doesn't allow me to filter out certain contacts in a view unless I uncheck the "card" group from being visible.

So, how can I get rid of it?
