Draw Area seems to have some issues. Below are two identified scenarios:
I select an event in first step, then in 2nd step I click on Draw Area. Then, I go back to the previous step and change my event selections (e.g. add/remove markers). Going back on the 2nd step again, clicking on Draw Area does not do anything. Only way it works is that I'll change one of the radiuses (e.g. 15->20)
In above scenario, if I clear the data on the map, then I'll click on Draw Area, it gets the Stations globally and it does not draw any circles on the map.
