Classic block menu button – undefined values

Thanks for creating such a useful tool for restaurants and cafes.

I understand the principal for adding menu groups using the shortcode process, which works fine. However, when I add a selection of groups by using the Menu button on the classic block tools, the shortcode that is generated has undefined values:

[brm_restaurant_menu groups="" show_group_title="undefined" show_group_desc="undefined" show_items="undefined" view="undefined"]

This seems a much simpler way to implement the menu for no technical users, so it would be helpful if this was functional. Can you offer any advice?

Thanks.
