Inconsistent query result

Users Dgraph

I have the same problem in DQL.
Schema:

connection: uid .
name: string .

type node {
    name
    connection
}

The connection predicate of a single node is updated several times to different other nodes.

When querying

{
    q(func: uid(0x123)){
        uid
        connection {
            uid
        }
    }
}

I get this result, where 0x1 and 0x2 where previously set connections, which should not happen. The predicate is not defined as a uid list in the schema.

 "q": [
      {
        "uid": "0x123",
        "connection": {
          "uid": [
            "0x1",
            "0x2"
          ]
        }
      }
    ]

But when querying

{
    q(func: uid(0x123)){
        uid
        connection {
            uid
            name
        }
    }
}

I get the correct result only containing the last set node.

 "q": [
      {
        "uid": "0x123",
        "connection": {
          "uid": "0x2",
          "name": "node2"
        }
      }
    ]

So it seems dgraph somehow does not delete the old edge when updating a connection. This also only happened when using dgraph version 24.1.0 or 24.1.1 instead of 24.0.0.
