Field group with special character breaks URL(likely an addon feature)

[apermo]

I created a field group called "Meine Themen / Meine Stadt", the URL for it is: /benutzerdaten-bearbeiten/meine-themen-%2F-meine-stadt and this triggers a system 404.

To fix this on my side, i'll just rename the group for now, but it would be nice if the field groups would simply come with a "slug" option, where you could manually define the slug, and it would be prefilled with sanitize_name( $fieldname );
