REST API returns two links

Old Versions
#1
Hello, I am trying REST service and have question.
 
I define two class "Server","Feature" and a domain "Relation".  I create one links "Server"->"Feature".
Next I retrieved the link via REST /cmdbuild/services/rest/v1/domains/{Id}/relations .
 
I expect only one result but API returns two results.
 
{"data": [
 
{ "_destinationDescription":"Test001",
"_sourceId":46,
"_type":"Relation",
"_destinationId":38,
"_id":52,
"_destinationType":"Server",
"_sourceType":"Feature",
"_sourceDescription":"3462512373502032751"},
 
{ "_destinationDescription":"3462512373502032751",
"_sourceId":38,
"_type":"Relation",
"_destinationId":46,
"_id":52,
"_destinationType":"Feature",
"_sourceType":"Server",
"_sourceDescription":"Test001"}
],
"meta":{"total":2}
}
 
It seems API generates id 46->38 and 38->46 from single actual link ID 52.
Is this behavior is intended results?
 
Thank you for your help.
