   ### Bug Type (问题类型)
   
   _No response_
   
   ### Before submit
   
   - [X] 我已经确认现有的 [Issues](https://github.com/hugegraph/hugegraph/issues) 与 
[FAQ](https://hugegraph.github.io/hugegraph-doc/guides/faq.html) 中没有相同 / 重复问题
   
   ### Environment (环境信息)
   
   - Server Version: v0.12.0
   - Backend: memory
   - OS: CentOS
   - Data Size:  100 vertices, 200 edges
   
   
   ### Expected & Actual behavior (期望与实际表现)
   
   We execute the query `g.V().inE('el0').hasLabel('el0','el1')` and expect it 
returns some edges. 
   
   But it throws an exception `java.lang.IllegalStateException: Illegal key 
'LABEL' with more than one value`.
   
   ### Reproduce
   
   The schema of the simplify graph as follows.
   
   ```
   
connection.getHugespecial().schema().propertyKey("ep0").asBoolean().ifNotExist().create();
   
connection.getHugespecial().schema().propertyKey("ep1").asBoolean().ifNotExist().create();
   
connection.getHugespecial().schema().edgeLabel("el0").sourceLabel("vl0").targetLabel("vl0").properties("ep0").ifNotExist().create();
     
   
connection.getHugespecial().schema().edgeLabel("el1").sourceLabel("vl0").targetLabel("vl0").properties("ep1").ifNotExist().create();
   
connection.getHugespecial().schema().indexLabel("el0Byep0").onE("el0").by("ep0").shard().ifNotExist().create();
   
connection.getHugespecial().schema().indexLabel("el1Byep0").onE("el1").by("ep1").shard().ifNotExist().create();
   
   Vertex vertex1 = new Vertex("vl0").property("vp0", true);
   Vertex vertex2 = new Vertex("vl0").property("vp0", false);
   Vertex vertex3 = new Vertex("vl0").property("vp0", true);
   graph.addVertices(Arrays.asList(vertex1, vertex2, vertex3));
   
   Edge edge1 = new Edge("el0").source(vertex1).target(vertex2).property("ep0", 
true);
   Edge edge2 = new Edge("el1").source(vertex1).target(vertex3).property("ep1", 
false);
   graph.addEdges(Arrays.asList(edge1, edge2));
   
   GremlinManager gremlin = connection.getHugespecial().gremlin();
   
   String query = "g.V().inE('el0').hasLabel('el0','el1')";
   
   ### Vertex/Edge example (问题点 / 边数据举例)
   
   _No response_
   
   ### Schema [VertexLabel, EdgeLabel, IndexLabel] (元数据结构)
   
   _No response_
