Wrong matching result on multiple labels

[ddaa2000]

Execute the following queries in RedisGraph 2.8.20

CREATE (n0 :L1)-[r1 :T0]->(n2)<-[r3 :T1]-(n4 :L2), (n2)<-[r4 :T2]-(n5 :L2)
MATCH (n0 :L2 :L1) RETURN * 

The correct result should be empty. However, RedisGraph returned the node with Label L1.
The CREATE query above can create the correct graph. If any of the the above n4 or n5 or the label of n0, n4, n5 is deleted in the CREATE query, the error would not be reproduced. It seems that RedisGraph puzzled when faced with multiple nodes with both L1 and L2.

@ddaa2000 thank you again!

Note the difference:

GRAPH.QUERY q "MATCH (n0:L2:L1) RETURN *"
1) 1) "n0"
2) 1) 1) 1) 1) "id"
            2) (integer) 0
         2) 1) "labels"
            2) 1) "L1"
         3) 1) "properties"
            2) (empty array)
3) 1) "Cached execution: 1"
   2) "Query internal execution time: 1.465200 milliseconds"

GRAPH.QUERY q "MATCH (n0:L1:L2) RETURN *"
1) 1) "n0"
2) (empty array)
3) 1) "Cached execution: 1"
   2) "Query internal execution time: 0.609800 milliseconds"
