Hey there,
That is the intended behavior. Before, it was a bug. There is no option to make the sub-indicator a separate control since it’s a single unit with the menu text. It could be possible with custom development but that would be outside the scope of our support. We do have an in-house custom development team that offer paid services, who may be able to assist. They can be contacted at pinnacle@theme.co if this is of interest to you.
The other solution for this would be to use UberMenu. UberMenu has more menu controls. Please see http://sevenspark.com/docs/ubermenu-3/responsive/touch and the documentation in general.
Thanks.
