Sort custom post type by most current date picker

So thanks to Jacob Peattie and his helpful comments I was able to resolve this issue.

meta_key was part of the group, but it wasnt prefixed by a group key. So, something like this totally works for me: group_field_sub_field. So changing that in both arrays did the trick.
