3 d map regional map problem

[richard3x3]

I created a map with 3 d Map Montreal's uiing open data for 311 calls, I selected a subset for calls regarding calls for rat extermination. The data has geo location for each call. I then tried to amend the tour to a regional map with electorial district by importing a kml file that was also on the the open data site. My file seems to import corectly because I recieved a message of 0 invalid values. However the district does not display the district polygons.
Suggestion or a reference to a how to video please.
