Using Logistics API for route optimzation

[MalindaWeeraratne]

I'm trying to use https://logistics.arcgis.com/arcgis/rest/services/World/VehicleRoutingProblem 

to find an optimized route for multiple delivery vehicles. However when I'm checking this with some locations in Switzerland, the returned route output shows a different location somewhere in Switzerland.

I'm using developer account for testing purpose and is there any configuration to do to return the correct output ?

I used below coordinates as the depot. 

"geometry" : {

"x" : 46.5390414392,

"y" : 6.6546267712

}

But it shows the route starting from 

[
     46.614652361000026,
     6.7049359840000307
 ] 

which is far way from the exact location.

Thanks in advance.
