When changing the ACL associated to an existing Service Function Classifer, the old <ACL, Classifier> entry is not deleted (which is the expected behavior), as a result two <ACL, Classifier> entries exist, the old one and the new one; e.g.:

{
"access-lists-state": {
"access-list-state": [
{
"acl-type": "ietf-access-control-list:ipv4-acl",
"acl-name": "ACL1",
"acl-service-function-classifier": [

{ "name": "Classifier1" ***** THE OLD ONE ***** }

]
},
{
"acl-type": "ietf-access-control-list:ipv4-acl",
"acl-name": "ACL2",
"acl-service-function-classifier": [

{ "name": "Classifier1" ***** THE NEW ONE ***** }

]
}
]
}
}
