Hi. Yes, of course) 

In Sydney exactly, where there are transitions stations have two stop_areas, and the transition between them is labeled stop_area_group. 

Our station has two stop areas in different parts, they should have different stop_areas and since there is a pedestrian crossing on the diagram these stop_areas should be combined into a stop_area_group.

Initially, this was correct. I've reverted it back to how it should be)
