Match Command in Qlikview - neo4j

Question

I have created only one graph in Neo4j using the create statement. Now I want to retrieve data from the same graph using the MATCH command. It is giving me the correct count of all the nodes and relationships. Now I have run the same create query again without any changes and now if I retrieve the count using the same MATCH then I'm getting the double value.If run it again then triple value. If I give the return statement in the create statement then the count is correct, if I give it separately then the count is getting multiplied.
Why it is so.
And how to get the correct count if I run the same graph multiple times.
LOAD CSV FROM "file:D:\\Neo4j\\demo2dbcopy.csv" AS emp
MERGE (root:SubGraph {source: emp[7]})
MERGE (cname:Cmpname {name: emp[0]})
MERGE (clusters:ClustName { name: emp [1]})
MERGE (dom:domains { name: emp [2]})
MERGE (Hd:Head { name: emp [3]})
MERGE (DelHd:DeliveryHead { name: emp [4]})
MERGE (Mgr:Managers { name: emp [5]})
MERGE (Emp:Employees { name: emp [6]})
CREATE (root)<-[:PART_OF_SUB_GRAPH]-(cname)-[:has]->(clusters),(clusters)-[:contains]->(dom)<-[:headedby]-(Hd),
(Hd)-[:equals]->(DelHd),
(DelHd)-[:assistedby]->(Mgr),
(Mgr)-[:Dividesinto]->(Emp)
return root,cname,clusters,dom,Hd,count(Hd);
and the MATCH statement is
MATCH (root:SubGraph {source: "demo2db"})<--(cname:Cmpname)-->(clusters:ClustName)-->(dom:domains {name:"BIDW"})<-[:headedby]-(Hd:Head) RETURN dom.name, count (Hd);
Thanks in advance...

The create command is
LOAD CSV FROM "file:D:\\Neo4j\\demo2dbcopy.csv" AS emp
MERGE (root:SubGraph {source: emp[7]})
MERGE (cname:Cmpname {name: emp[0]})
MERGE (clusters:ClustName { name: emp [1]})
MERGE (dom:domains { name: emp [2]})
MERGE (Hd:Head { name: emp [3]})
MERGE (DelHd:DeliveryHead { name: emp [4]})
MERGE (Mgr:Managers { name: emp [5]})
MERGE (Emp:Employees { name: emp [6]})
CREATE (root)<-[:PART_OF_SUB_GRAPH]-(cname)-[:has]->(clusters),(clusters)-[:contains]->(dom)<-[:headedby]-(Hd),
(Hd)-[:equals]->(DelHd),
(DelHd)-[:assistedby]->(Mgr),
(Mgr)-[:Dividesinto]->(Emp)
return root,cname,clusters,dom,Hd,count(Hd);
and the MATCH statement is
MATCH (root:SubGraph {source: "demo2db"})<--(cname:Cmpname)-->(clusters:ClustName)-->(dom:domains {name:"BIDW"})<-[:headedby]-(Hd:Head) RETURN count (Hd);
